If the Medusa application is running in a development environment, a spinner starts to show the activity's progress. - -For example: - -```ts title="src/jobs/log-message.ts" -import { MedusaContainer } from "@medusajs/framework/types" -import { ContainerRegistrationKeys } from "@medusajs/framework/utils" - -export default async function myCustomJob( - container: MedusaContainer -) { - const logger = container.resolve(ContainerRegistrationKeys.LOGGER) - - const activityId = logger.activity("First log message") - - logger.progress(activityId, `Second log message`) - - logger.success(activityId, "Last log message") -} -``` - -The `activity` method returns the ID of the started activity. This ID can then be passed to one of the following methods of the `Logger` class: - -- `progress`: Log a message of level `info` that indicates progress within that same activity. -- `success`: Log a message of level `info` that indicates that the activity has succeeded. This also ends the associated activity. -- `failure`: Log a message of level `error` that indicates that the activity has failed. This also ends the associated activity. - -If you configured the `LOG_LEVEL` environment variable to a level higher than those associated with the above methods, their messages won’t be logged. - - -# Medusa Testing Tools - -In this chapter, you'll learn about Medusa's testing tools and how to install and configure them. - -## @medusajs/test-utils Package - -Medusa provides a Testing Framework to create integration tests for your custom API routes, modules, or other Medusa customizations. - -To use the Testing Framework, install `@medusajs/test-utils` as a `devDependency`: - -```bash npm2yarn -npm install --save-dev @medusajs/test-utils@latest -``` - -*** - -## Install and Configure Jest - -Writing tests with `@medusajs/test-utils`'s tools requires installing and configuring Jest in your project. - -Run the following command to install the required Jest dependencies: - -```bash npm2yarn -npm install --save-dev jest @types/jest @swc/jest -``` - -Then, create the file `jest.config.js` with the following content: - -```js title="jest.config.js" -const { loadEnv } = require("@medusajs/framework/utils") -loadEnv("test", process.cwd()) - -module.exports = { - transform: { - "^.+\\.[jt]s$": [ - "@swc/jest", - { - jsc: { - parser: { syntax: "typescript", decorators: true }, - }, - }, - ], - }, - testEnvironment: "node", - moduleFileExtensions: ["js", "ts", "json"], - modulePathIgnorePatterns: ["dist/"], - setupFiles: ["./integration-tests/setup.js"], -} - -if (process.env.TEST_TYPE === "integration:http") { - module.exports.testMatch = ["**/integration-tests/http/*.spec.[jt]s"] -} else if (process.env.TEST_TYPE === "integration:modules") { - module.exports.testMatch = ["**/src/modules/*/__tests__/**/*.[jt]s"] -} else if (process.env.TEST_TYPE === "unit") { - module.exports.testMatch = ["**/src/**/__tests__/**/*.unit.spec.[jt]s"] -} -``` - -Next, create the `integration-tests/setup.js` file with the following content: - -```js title="integration-tests/setup.js" -const { MetadataStorage } = require("@mikro-orm/core") - -MetadataStorage.clear() -``` - -*** - -## Add Test Commands - -Finally, add the following scripts to `package.json`: - -```json title="package.json" -"scripts": { - // ... - "test:integration:http": "TEST_TYPE=integration:http NODE_OPTIONS=--experimental-vm-modules jest --silent=false --runInBand --forceExit", - "test:integration:modules": "TEST_TYPE=integration:modules NODE_OPTIONS=--experimental-vm-modules jest --silent --runInBand --forceExit", - "test:unit": "TEST_TYPE=unit NODE_OPTIONS=--experimental-vm-modules jest --silent --runInBand --forceExit" -}, -``` - -You now have two commands: - -- `test:integration:http` to run integration tests (for example, for API routes and workflows) available under the `integration-tests/http` directory. -- `test:integration:modules` to run integration tests for modules available in any `__tests__` directory under `src/modules`. -- `test:unit` to run unit tests in any `__tests__` directory under the `src` directory. - -Medusa's Testing Framework works for integration tests only.

PostgreSQL database: This is the database that will hold your Medusa application's details. -2. Redis database: This is the database that will store the Medusa server's session. -3. Medusa application in [server and worker mode](https://docs.medusajs.com/learn/production/worker-mode/index.html.md), where: - - The server mode handles incoming API requests and serving the Medusa Admin dashboard. - - The worker mode handles background tasks, such as scheduled jobs and subscribers. - -So, when choosing a hosting provider, make sure it supports deploying these resources. Also, for optimal experience, the hosting provider and plan must offer at least 2GB of RAM. - -*** - -## 1. Configure Medusa Application - -### Worker Mode - -The `workerMode` configuration determines which mode the Medusa application runs in. When you deploy the Medusa application, you deploy two instances: one in server mode, and one in worker mode. - -Learn more about worker mode in the [Worker Module chapter](https://docs.medusajs.com/learn/production/worker-mode/index.html.md). - -So, add the following configuration in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - // ... - workerMode: process.env.MEDUSA_WORKER_MODE as "shared" | "worker" | "server", - }, -}) -``` - -Later, you’ll set different values of the `MEDUSA_WORKER_MODE` environment variable for each Medusa application deployment or instance. - -### Configure Medusa Admin - -The Medusa Admin is served by the Medusa server application. So, you need to disable it in the worker Medusa application only. - -To disable the Medusa Admin in the worker Medusa application while keeping it enabled in the server Medusa application, add the following configuration in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - admin: { - disable: process.env.DISABLE_MEDUSA_ADMIN === "true", - }, -}) -``` - -Later, you’ll set different values of the `DISABLE_MEDUSA_ADMIN` environment variable for each Medusa application instance. - -### Configure Redis URL - -The `redisUrl` configuration specifies the connection URL to Redis to store the Medusa server's session. - -Learn more in the [Medusa Configuration documentation](https://docs.medusajs.com/learn/configurations/medusa-config#redisurl/index.html.md). - -So, add the following configuration in `medusa-config.ts` : - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - projectConfig: { - // ... - redisUrl: process.env.REDIS_URL, - }, -}) -``` - -*** - -## 2. Add predeploy Script - -Before you start the Medusa application in production, you should always run migrations and sync links. - -So, add the following script in `package.json`: - -```json -"scripts": { - // ... - "predeploy": "medusa db:migrate" -}, -``` - -*** - -## 3. Install Production Modules and Providers - -By default, your Medusa application uses modules and providers useful for development, such as the In-Memory Cache Module or the Local File Module Provider. - -It’s highly recommended to instead use modules and providers suitable for production, including: - -- [Redis Cache Module](https://docs.medusajs.com/resources/infrastructure-modules/cache/redis/index.html.md) -- [Redis Event Bus Module](https://docs.medusajs.com/resources/infrastructure-modules/event/redis/index.html.md) -- [Workflow Engine Redis Module](https://docs.medusajs.com/resources/infrastructure-modules/workflow-engine/redis/index.html.md) -- [S3 File Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/file/s3/index.html.md) (or other file module providers production-ready). -- [SendGrid Notification Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/notification/sendgrid/index.html.md) (or other notification module providers production-ready). - -Then, add these modules in `medusa-config.ts`: - -```ts title="medusa-config.ts" -import { Modules } from "@medusajs/framework/utils" - -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "@medusajs/medusa/cache-redis", - options: { - redisUrl: process.env.REDIS_URL, - }, - }, - { - resolve: "@medusajs/medusa/event-bus-redis", - options: { - redisUrl: process.env.REDIS_URL, - }, - }, - { - resolve: "@medusajs/medusa/workflow-engine-redis", - options: { - redis: { - url: process.env.REDIS_URL, - }, - }, - }, - ], -}) -``` - -Check out the [Integrations](https://docs.medusajs.com/resources/integrations/index.html.md) and [Infrastructure Modules](https://docs.medusajs.com/resources/infrastructure-modules/index.html.md) documentation for other modules and providers to use. - -*** - -## 4. Create PostgreSQL and Redis Databases - -Your Medusa application must connect to PostgreSQL and Redis databases. So, before you deploy it, create production PostgreSQL and Redis databases. - -If your hosting provider doesn't support databases, you can use [Neon for PostgreSQL database hosting](https://neon.tech/), and [Redis Cloud for the Redis database hosting](https://redis.io/cloud/). - -After hosting both databases, keep their connection URLs for the next steps. - -*** - -## 5. Deploy Medusa Application in Server Mode - -As mentioned earlier, you'll deploy two instances or create two deployments of your Medusa application: one in server mode, and the other in worker mode. - -The deployment steps depend on your hosting provider. This section provides the general steps to perform during the deployment. - -### Set Environment Variables - -When setting the environment variables of the Medusa application, set the following variables: - -```bash -COOKIE_SECRET=supersecret # TODO GENERATE SECURE SECRET -JWT_SECRET=supersecret # TODO GENERATE SECURE SECRET -STORE_CORS= # STOREFRONT URL -ADMIN_CORS= # ADMIN URL -AUTH_CORS= # STOREFRONT AND ADMIN URLS, SEPARATED BY COMMAS -DISABLE_MEDUSA_ADMIN=false -MEDUSA_WORKER_MODE=server -PORT=9000 -DATABASE_URL # POSTGRES DATABASE URL -REDIS_URL= # REDIS DATABASE URL -``` - -Where: - -- The value of `COOKIE_SECRET` and `JWT_SECRET` must be a randomly generated secret. -- `STORE_CORS`'s value is the URL of your storefront. If you don’t have it yet, you can skip adding it for now. -- `ADMIN_CORS`'s value is the URL of the admin dashboard, which is the same as the server Medusa application. You can add it later if you don't currently have it. -- `AUTH_CORS`'s value is the URLs of any application authenticating users, customers, or other actor types, such as the storefront and admin URLs. The URLs are separated by commas. If you don’t have the URLs yet, you can set its value later. -- Set `DISABLE_MEDUSA_ADMIN`'s value to `false` so that the admin is built with the server application. -- Set the PostgreSQL database's connection URL as the value of `DATABASE_URL` -- Set the Redis database's connection URL as the value of `REDIS_URL`. - -Feel free to add any other relevant environment variables, such as for integrations and Infrastructure Modules. If you're using environment variables in your admin customizations, make sure to set them as well, as they're inlined during the build process. - -### Set Start Command - -The Medusa application's production build, which is created using the `build` command, outputs the Medusa application to `.medusa/server`. So, you must install the dependencies in the `.medusa/server` directory, then run the `start` command in it. - -If your hosting provider doesn't support setting a current-working directory, set the start command to the following: - -```bash npm2yarn -cd .medusa/server && npm install && npm run predeploy && npm run start -``` - -Notice that you run the `predeploy` command before starting the Medusa application to run migrations and sync links whenever there's an update. - -### Set Backend URL in Admin Configuration - -The Medusa Admin is built and hosted statically. To send requests to the Medusa server application, you must set the backend URL in the Medusa Admin's configuration. - -After you’ve obtained the Medusa application’s URL, add the following configuration to `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - admin: { - // ... - backendUrl: process.env.MEDUSA_BACKEND_URL, - }, -}) -``` - -Then, push the changes to the GitHub repository or deployed application. - -In your hosting provider, add or modify the following environment variables for the Medusa application in server mode: - -```bash -ADMIN_CORS= # MEDUSA APPLICATION URL -AUTH_CORS= # ADD MEDUSA APPLICATION URL -MEDUSA_BACKEND_URL= # URL TO DEPLOYED MEDUSA APPLICATION -``` - -Where you set the value of `ADMIN_CORS` and `MEDUSA_BACKEND_URL` to the Medusa application’s URL, and you add the URL to `AUTH_CORS`. - -After setting the environment variables, make sure to restart the deployment for the changes to take effect. - -Remember to separate URLs in `AUTH_CORS` by commas. - -*** - -## 6. Deploy Medusa Application in Worker Mode - -Next, you'll deploy the Medusa application in worker mode. - -As explained in the previous section, the deployment steps depend on your hosting provider. This section provides the general steps to perform during the deployment. - -### Set Environment Variables - -When setting the environment variables of the Medusa application, set the following variables: - -```bash -COOKIE_SECRET=supersecret # TODO GENERATE SECURE SECRET -JWT_SECRET=supersecret # TODO GENERATE SECURE SECRET -DISABLE_MEDUSA_ADMIN=true -MEDUSA_WORKER_MODE=worker -PORT=9000 -DATABASE_URL # POSTGRES DATABASE URL -REDIS_URL= # REDIS DATABASE URL -``` - -Where: - -- The value of `COOKIE_SECRET` and `JWT_SECRET` must be a randomly generated secret. -- Set `DISABLE_MEDUSA_ADMIN`'s value to `true` so that the admin isn't built with the worker application. -- Set the PostgreSQL database's connection URL as the value of `DATABASE_URL` -- Set the Redis database's connection URL as the value of `REDIS_URL`. - -Feel free to add any other relevant environment variables, such as for integrations and Infrastructure Modules. - -### Set Start Command - -The Medusa application's production build, which is created using the `build` command, outputs the Medusa application to `.medusa/server`.

It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. - -You create a data model in a [module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md). The module's service provides the methods to store and manage those data models. Then, you can resolve the module's service in other customizations, such as a [workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md), to manage the data models' records. - -*** - -## How to Create a Data Model - -In a module, you can create a data model in a TypeScript or JavaScript file under the module's `models` directory. - -So, for example, assuming you have a Blog Module at `src/modules/blog`, you can create a `Post` data model by creating the `src/modules/blog/models/post.ts` file with the following content: - -![Updated directory overview after adding the data model](https://res.cloudinary.com/dza7lstvk/image/upload/v1732806790/Medusa%20Book/blog-dir-overview-1_jfvovj.jpg) - -```ts title="src/modules/blog/models/post.ts" -import { model } from "@medusajs/framework/utils" - -const Post = model.define("post", { - id: model.id().primaryKey(), - title: model.text(), -}) - -export default Post -``` - -You define the data model using the `define` method of the DML. It accepts two parameters: - -1. The first one is the name of the data model's table in the database. Use snake-case names. -2. The second is an object, which is the data model's schema. The schema's properties are defined using the `model`'s methods, such as `text` and `id`. - - Data models automatically have the date properties `created_at`, `updated_at`, and `deleted_at`, so you don't need to add them manually. - -The code snippet above defines a `Post` data model with `id` and `title` properties. - -*** - -## Generate Migrations - -After you create a data model in a module, then [register that module in your Medusa configurations](https://docs.medusajs.com/learn/fundamentals/modules#4-add-module-to-medusas-configurations/index.html.md), you must generate a migration to create the data model's table in the database. - -A migration is a TypeScript or JavaScript file that defines database changes made by a module.

Medusa application in [server and worker mode](https://docs.medusajs.com/learn/production/worker-mode/index.html.md), where: + - The server mode handles incoming API requests and serving the Medusa Admin dashboard. + - The worker mode handles background tasks, such as scheduled jobs and subscribers. + +So, when choosing a hosting provider, make sure it supports deploying these resources. Also, for optimal experience, the hosting provider and plan must offer at least 2GB of RAM. + +*** + +## 1. Configure Medusa Application + +### Worker Mode + +The `workerMode` configuration determines which mode the Medusa application runs in. When you deploy the Medusa application, you deploy two instances: one in server mode, and one in worker mode. + +Learn more about worker mode in the [Worker Module chapter](https://docs.medusajs.com/learn/production/worker-mode/index.html.md). + +So, add the following configuration in `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + projectConfig: { + // ... + workerMode: process.env.MEDUSA_WORKER_MODE as "shared" | "worker" | "server", + }, +}) +``` + +Later, you’ll set different values of the `MEDUSA_WORKER_MODE` environment variable for each Medusa application deployment or instance. + +### Configure Medusa Admin + +The Medusa Admin is served by the Medusa server application.

Install Production Modules and Providers + +By default, your Medusa application uses modules and providers useful for development, such as the In-Memory Cache Module or the Local File Module Provider. + +It’s highly recommended to instead use modules and providers suitable for production, including: + +- [Redis Cache Module](https://docs.medusajs.com/resources/infrastructure-modules/cache/redis/index.html.md) +- [Redis Event Bus Module](https://docs.medusajs.com/resources/infrastructure-modules/event/redis/index.html.md) +- [Workflow Engine Redis Module](https://docs.medusajs.com/resources/infrastructure-modules/workflow-engine/redis/index.html.md) +- [S3 File Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/file/s3/index.html.md) (or other file module providers production-ready). +- [SendGrid Notification Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/notification/sendgrid/index.html.md) (or other notification module providers production-ready). + +Then, add these modules in `medusa-config.ts`: + +```ts title="medusa-config.ts" +import { Modules } from "@medusajs/framework/utils" + +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/cache-redis", + options: { + redisUrl: process.env.REDIS_URL, + }, + }, + { + resolve: "@medusajs/medusa/event-bus-redis", + options: { + redisUrl: process.env.REDIS_URL, + }, + }, + { + resolve: "@medusajs/medusa/workflow-engine-redis", + options: { + redis: { + url: process.env.REDIS_URL, + }, + }, + }, + ], +}) +``` + +Check out the [Integrations](https://docs.medusajs.com/resources/integrations/index.html.md) and [Infrastructure Modules](https://docs.medusajs.com/resources/infrastructure-modules/index.html.md) documentation for other modules and providers to use. + +*** + +## 4. Create PostgreSQL and Redis Databases + +Your Medusa application must connect to PostgreSQL and Redis databases. So, before you deploy it, create production PostgreSQL and Redis databases. + +If your hosting provider doesn't support databases, you can use [Neon for PostgreSQL database hosting](https://neon.tech/), and [Redis Cloud for the Redis database hosting](https://redis.io/cloud/). + +After hosting both databases, keep their connection URLs for the next steps. + +*** + +## 5. Deploy Medusa Application in Server Mode + +As mentioned earlier, you'll deploy two instances or create two deployments of your Medusa application: one in server mode, and the other in worker mode. + +The deployment steps depend on your hosting provider. This section provides the general steps to perform during the deployment. + +### Set Environment Variables + +When setting the environment variables of the Medusa application, set the following variables: + +```bash +COOKIE_SECRET=supersecret # TODO GENERATE SECURE SECRET +JWT_SECRET=supersecret # TODO GENERATE SECURE SECRET +STORE_CORS= # STOREFRONT URL +ADMIN_CORS= # ADMIN URL +AUTH_CORS= # STOREFRONT AND ADMIN URLS, SEPARATED BY COMMAS +DISABLE_MEDUSA_ADMIN=false +MEDUSA_WORKER_MODE=server +PORT=9000 +DATABASE_URL # POSTGRES DATABASE URL +REDIS_URL= # REDIS DATABASE URL +``` + +Where: + +- The value of `COOKIE_SECRET` and `JWT_SECRET` must be a randomly generated secret. +- `STORE_CORS`'s value is the URL of your storefront. If you don’t have it yet, you can skip adding it for now. +- `ADMIN_CORS`'s value is the URL of the admin dashboard, which is the same as the server Medusa application. You can add it later if you don't currently have it. +- `AUTH_CORS`'s value is the URLs of any application authenticating users, customers, or other actor types, such as the storefront and admin URLs. The URLs are separated by commas. If you don’t have the URLs yet, you can set its value later. +- Set `DISABLE_MEDUSA_ADMIN`'s value to `false` so that the admin is built with the server application. +- Set the PostgreSQL database's connection URL as the value of `DATABASE_URL` +- Set the Redis database's connection URL as the value of `REDIS_URL`. + +Feel free to add any other relevant environment variables, such as for integrations and Infrastructure Modules. If you're using environment variables in your admin customizations, make sure to set them as well, as they're inlined during the build process. + +### Set Start Command + +The Medusa application's production build, which is created using the `build` command, outputs the Medusa application to `.medusa/server`. So, you must install the dependencies in the `.medusa/server` directory, then run the `start` command in it. + +If your hosting provider doesn't support setting a current-working directory, set the start command to the following: + +```bash npm2yarn +cd .medusa/server && npm install && npm run predeploy && npm run start +``` + +Notice that you run the `predeploy` command before starting the Medusa application to run migrations and sync links whenever there's an update. + +### Set Backend URL in Admin Configuration + +The Medusa Admin is built and hosted statically. To send requests to the Medusa server application, you must set the backend URL in the Medusa Admin's configuration. + +After you’ve obtained the Medusa application’s URL, add the following configuration to `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + admin: { + // ... + backendUrl: process.env.MEDUSA_BACKEND_URL, + }, +}) +``` + +Then, push the changes to the GitHub repository or deployed application. + +In your hosting provider, add or modify the following environment variables for the Medusa application in server mode: + +```bash +ADMIN_CORS= # MEDUSA APPLICATION URL +AUTH_CORS= # ADD MEDUSA APPLICATION URL +MEDUSA_BACKEND_URL= # URL TO DEPLOYED MEDUSA APPLICATION +``` + +Where you set the value of `ADMIN_CORS` and `MEDUSA_BACKEND_URL` to the Medusa application’s URL, and you add the URL to `AUTH_CORS`. + +After setting the environment variables, make sure to restart the deployment for the changes to take effect. + +Remember to separate URLs in `AUTH_CORS` by commas. + +*** + +## 6. Deploy Medusa Application in Worker Mode + +Next, you'll deploy the Medusa application in worker mode. + +As explained in the previous section, the deployment steps depend on your hosting provider. This section provides the general steps to perform during the deployment. + +### Set Environment Variables + +When setting the environment variables of the Medusa application, set the following variables: + +```bash +COOKIE_SECRET=supersecret # TODO GENERATE SECURE SECRET +JWT_SECRET=supersecret # TODO GENERATE SECURE SECRET +DISABLE_MEDUSA_ADMIN=true +MEDUSA_WORKER_MODE=worker +PORT=9000 +DATABASE_URL # POSTGRES DATABASE URL +REDIS_URL= # REDIS DATABASE URL +``` + +Where: + +- The value of `COOKIE_SECRET` and `JWT_SECRET` must be a randomly generated secret. +- Set `DISABLE_MEDUSA_ADMIN`'s value to `true` so that the admin isn't built with the worker application. +- Set the PostgreSQL database's connection URL as the value of `DATABASE_URL` +- Set the Redis database's connection URL as the value of `REDIS_URL`. + +Feel free to add any other relevant environment variables, such as for integrations and Infrastructure Modules. + +### Set Start Command + +The Medusa application's production build, which is created using the `build` command, outputs the Medusa application to `.medusa/server`.

Test Deployed Application + +Once the application is deployed and live, go to `/health`, where `` is the URL of the Medusa application in server mode. If the deployment was successful, you’ll see the `OK` response. + +The Medusa Admin is also available at `/app`. + +*** + +## Create Admin User + +If your hosting provider supports running commands in your Medusa application's directory, run the following command to create an admin user: + +```bash +npx medusa user -e admin-medusa@test.com -p supersecret +``` + +Replace the email `admin-medusa@test.com` and password `supersecret` with the credentials you want. + +You can use these credentials to log into the Medusa Admin dashboard. + + +# Worker Mode of Medusa Instance + +In this chapter, you'll learn about the different modes of running a Medusa instance and how to configure the mode. + +## What is Worker Mode? + +By default, the Medusa application runs both the server, which handles all incoming requests, and the worker, which processes background tasks, in a single process.

Create the API Route - -You create an API route in a `route.{ts,js}` file under a sub-directory of the `src/api` directory. The file exports API Route handler functions for at least one HTTP method (`GET`, `POST`, `DELETE`, etc…). - -Learn more about API routes [in this guide](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md). - -The route's path is the path of `route.{ts,js}` relative to `src/api`. So, to create the API route at `/admin/brands`, create the file `src/api/admin/brands/route.ts` with the following content: - -![Directory structure of the Medusa application after adding the route](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869882/Medusa%20Book/brand-route-dir-overview-2_hjqlnf.jpg) - -```ts title="src/api/admin/brands/route.ts" -import { - MedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { - createBrandWorkflow, -} from "../../../workflows/create-brand" - -type PostAdminCreateBrandType = { - name: string -} - -export const POST = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - const { result } = await createBrandWorkflow(req.scope) - .run({ - input: req.validatedBody, - }) - - res.json({ brand: result }) -} -``` - -You export a route handler function with its name (`POST`) being the HTTP method of the API route you're exposing. - -The function receives two parameters: a `MedusaRequest` object to access request details, and `MedusaResponse` object to return or manipulate the response. The `MedusaRequest` object's `scope` property is the [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) that holds Framework tools and custom and core modules' services. - -`MedusaRequest` accepts the request body's type as a type argument. - -In the API route's handler, you execute the `createBrandWorkflow` by invoking it and passing the Medusa container `req.scope` as a parameter, then invoking its `run` method. You pass the workflow's input in the `input` property of the `run` method's parameter. You pass the request body's parameters using the `validatedBody` property of `MedusaRequest`. - -You return a JSON response with the created brand using the `res.json` method. - -*** - -## 2. Create Validation Schema - -The API route you created accepts the brand's name in the request body. So, you'll create a schema used to validate incoming request body parameters. - -Medusa uses [Zod](https://zod.dev/) to create validation schemas. These schemas are then used to validate incoming request bodies or query parameters. - -Learn more about API route validation in [this chapter](https://docs.medusajs.com/learn/fundamentals/api-routes/validation/index.html.md). - -You create a validation schema in a TypeScript or JavaScript file under a sub-directory of the `src/api` directory. So, create the file `src/api/admin/brands/validators.ts` with the following content: - -![Directory structure of Medusa application after adding validators file](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869806/Medusa%20Book/brand-route-dir-overview-1_yfyjss.jpg) - -```ts title="src/api/admin/brands/validators.ts" -import { z } from "zod" - -export const PostAdminCreateBrand = z.object({ - name: z.string(), -}) -``` - -You export a validation schema that expects in the request body an object having a `name` property whose value is a string. - -You can then replace `PostAdminCreateBrandType` in `src/api/admin/brands/route.ts` with the following: - -```ts title="src/api/admin/brands/route.ts" -// ... -import { z } from "zod" -import { PostAdminCreateBrand } from "./validators" - -type PostAdminCreateBrandType = z.infer - -// ... -``` - -*** - -## 3. Add Validation Middleware - -A middleware is a function executed before the route handler when a request is sent to an API Route. It's useful to guard API routes, parse custom request body types, and apply validation on an API route. - -Learn more about middlewares in [this chapter](https://docs.medusajs.com/learn/fundamentals/api-routes/middlewares/index.html.md). - -Medusa provides a `validateAndTransformBody` middleware that accepts a Zod validation schema and returns a response error if a request is sent with body parameters that don't satisfy the validation schema. - -Middlewares are defined in the special file `src/api/middlewares.ts`. So, to add the validation middleware on the API route you created in the previous step, create the file `src/api/middlewares.ts` with the following content: - -![Directory structure of the Medusa application after adding the middleware](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869977/Medusa%20Book/brand-route-dir-overview-3_kcx511.jpg) - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - validateAndTransformBody, -} from "@medusajs/framework/http" -import { PostAdminCreateBrand } from "./admin/brands/validators" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/admin/brands", - method: "POST", - middlewares: [ - validateAndTransformBody(PostAdminCreateBrand), - ], - }, - ], -}) -``` - -You define the middlewares using the `defineMiddlewares` function and export its returned value. The function accepts an object having a `routes` property, which is an array of middleware objects. - -In the middleware object, you define three properties: - -- `matcher`: a string or regular expression indicating the API route path to apply the middleware on. You pass the create brand's route `/admin/brand`. -- `method`: The HTTP method to restrict the middleware to, which is `POST`. -- `middlewares`: An array of middlewares to apply on the route. You pass the `validateAndTransformBody` middleware, passing it the Zod schema you created earlier. - -The Medusa application will now validate the body parameters of `POST` requests sent to `/admin/brands` to ensure they match the Zod validation schema. If not, an error is returned in the response specifying the issues to fix in the request body. - -*** - -## Test API Route - -To test out the API route, start the Medusa application with the following command: - -```bash npm2yarn -npm run dev -``` - -Since the `/admin/brands` API route has a `/admin` prefix, it's only accessible by authenticated admin users. - -So, to retrieve an authenticated token of your admin user, send a `POST` request to the `/auth/user/emailpass` API Route: - -```bash -curl -X POST 'http://localhost:9000/auth/user/emailpass' \ --H 'Content-Type: application/json' \ ---data-raw '{ - "email": "admin@medusa-test.com", - "password": "supersecret" -}' -``` - -Make sure to replace the email and password with your admin user's credentials. - -Don't have an admin user? Refer to [this guide](https://docs.medusajs.com/learn/installation#create-medusa-admin-user/index.html.md). - -Then, send a `POST` request to `/admin/brands`, passing the token received from the previous request in the `Authorization` header: - -```bash -curl -X POST 'http://localhost:9000/admin/brands' \ --H 'Content-Type: application/json' \ --H 'Authorization: Bearer {token}' \ ---data '{ - "name": "Acme" -}' -``` - -This returns the created brand in the response: - -```json title="Example Response" -{ - "brand": { - "id": "01J7AX9ES4X113HKY6C681KDZJ", - "name": "Acme", - "created_at": "2024-09-09T08:09:34.244Z", - "updated_at": "2024-09-09T08:09:34.244Z" - } -} -``` - -*** - -## Summary - -By following the previous example chapters, you implemented a custom feature that allows admin users to create a brand. You did that by: - -1. Creating a module that defines and manages a `brand` table in the database. -2. Creating a workflow that uses the module's service to create a brand record, and implements the compensation logic to delete that brand in case an error occurs. -3. Creating an API route that allows admin users to create a brand. - -*** - -## Next Steps: Associate Brand with Product - -Now that you have brands in your Medusa application, you want to associate a brand with a product, which is defined in the [Product Module](https://docs.medusajs.com/resources/commerce-modules/product/index.html.md). - -In the next chapters, you'll learn how to build associations between data models defined in different modules. - - -# Guide: Implement Brand Module - -In this chapter, you'll build a Brand Module that adds a `brand` table to the database and provides data-management features for it. - -A module is a reusable package of functionalities related to a single domain or integration. Medusa comes with multiple pre-built modules for core commerce needs, such as the [Cart Module](https://docs.medusajs.com/resources/commerce-modules/cart/index.html.md) that holds the data models and business logic for cart operations. - -In a module, you create data models and business logic to manage them. In the next chapters, you'll see how you use the module to build commerce features. - -Learn more about modules in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md). - -## 1. Create Module Directory - -Modules are created in a sub-directory of `src/modules`. So, start by creating the directory `src/modules/brand` that will hold the Brand Module's files. - -![Directory structure in Medusa project after adding the brand directory](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868844/Medusa%20Book/brand-dir-overview-1_hxwvgx.jpg) - -*** - -## 2. Create Data Model - -A data model represents a table in the database. You create data models using Medusa's Data Model Language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. - -Learn more about data models in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#1-create-data-model/index.html.md). - -You create a data model in a TypeScript or JavaScript file under the `models` directory of a module. So, to create a data model that represents a new `brand` table in the database, create the file `src/modules/brand/models/brand.ts` with the following content: - -![Directory structure in module after adding the brand data model](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868920/Medusa%20Book/brand-dir-overview-2_lexhdl.jpg) - -```ts title="src/modules/brand/models/brand.ts" -import { model } from "@medusajs/framework/utils" - -export const Brand = model.define("brand", { - id: model.id().primaryKey(), - name: model.text(), -}) -``` - -You create a `Brand` data model which has an `id` primary key property, and a `name` text property. - -You define the data model using the `define` method of the DML. It accepts two parameters: - -1. The first one is the name of the data model's table in the database. Use snake-case names. -2. The second is an object, which is the data model's schema. - -Learn about other property types in [this chapter](https://docs.medusajs.com/learn/fundamentals/data-models/properties/index.html.md). - -*** - -## 3. Create Module Service - -You perform database operations on your data models in a service, which is a class exported by the module and acts like an interface to its functionalities. - -In this step, you'll create the Brand Module's service that provides methods to manage the `Brand` data model. In the next chapters, you'll use this service when exposing custom features that involve managing brands. - -Learn more about services in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#2-create-service/index.html.md). - -You define a service in a `service.ts` or `service.js` file at the root of your module's directory. So, create the file `src/modules/brand/service.ts` with the following content: - -![Directory structure in module after adding the service](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868984/Medusa%20Book/brand-dir-overview-3_jo7baj.jpg) - -```ts title="src/modules/brand/service.ts" highlights={serviceHighlights} -import { MedusaService } from "@medusajs/framework/utils" -import { Brand } from "./models/brand" - -class BrandModuleService extends MedusaService({ - Brand, -}) { - -} - -export default BrandModuleService -``` - -The `BrandModuleService` extends a class returned by `MedusaService` from the Modules SDK. This function generates a class with data-management methods for your module's data models. - -The `MedusaService` function receives an object of the module's data models as a parameter, and generates methods to manage those data models. So, the `BrandModuleService` now has methods like `createBrands` and `retrieveBrand` to manage the `Brand` data model. - -You'll use these methods in the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). - -Find a reference of all generated methods in [this guide](https://docs.medusajs.com/resources/service-factory-reference/index.html.md). - -*** - -## 4. Export Module Definition - -A module must export a definition that tells Medusa the name of the module and its main service. This definition is exported in an `index.ts` file at the module's root directory. - -So, to export the Brand Module's definition, create the file `src/modules/brand/index.ts` with the following content: - -![Directory structure in module after adding the definition file](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869045/Medusa%20Book/brand-dir-overview-4_nf8ymw.jpg) - -```ts title="src/modules/brand/index.ts" -import { Module } from "@medusajs/framework/utils" -import BrandModuleService from "./service" - -export const BRAND_MODULE = "brand" - -export default Module(BRAND_MODULE, { - service: BrandModuleService, -}) -``` - -You use `Module` from the Modules SDK to create the module's definition. It accepts two parameters: - -1. The module's name (`brand`). You'll use this name when you use this module in other customizations. -2. An object with a required property `service` indicating the module's main service. - -You export `BRAND_MODULE` to reference the module's name more reliably in other customizations. - -*** - -## 5. Add Module to Medusa's Configurations - -To start using your module, you must add it to Medusa's configurations in `medusa-config.ts`. - -The object passed to `defineConfig` in `medusa-config.ts` accepts a `modules` property, whose value is an array of modules to add to the application. So, add the following in `medusa-config.ts`: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/brand", - }, - ], -}) -``` - -The Brand Module is now added to your Medusa application. You'll start using it in the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). - -*** - -## 6. Generate and Run Migrations - -A migration is a TypeScript or JavaScript file that defines database changes made by a module. Migrations ensure that your module is re-usable and removes friction when working in a team, making it easy to reflect changes across team members' databases. - -Learn more about migrations in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#5-generate-migrations/index.html.md). - -[Medusa's CLI tool](https://docs.medusajs.com/resources/medusa-cli/index.html.md) allows you to generate migration files for your module, then run those migrations to reflect the changes in the database. So, run the following commands in your Medusa application's directory: - -```bash -npx medusa db:generate brand -npx medusa db:migrate -``` - -The `db:generate` command accepts as an argument the name of the module to generate the migrations for, and the `db:migrate` command runs all migrations that haven't been run yet in the Medusa application. - -*** - -## Next Step: Create Brand Workflow - -The Brand Module now creates a `brand` table in the database and provides a class to manage its records. - -In the next chapter, you'll implement the functionality to create a brand in a workflow. You'll then use that workflow in a later chapter to expose an endpoint that allows admin users to create a brand. - - -# Guide: Create Brand Workflow - -This chapter builds on the work from the [previous chapter](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) where you created a Brand Module. - -After adding custom modules to your application, you build commerce features around them using workflows. A workflow is a series of queries and actions, called steps, that complete a task spanning across modules. You construct a workflow similar to a regular function, but it's a special function that allows you to define roll-back logic, retry configurations, and more advanced features. - -The workflow you'll create in this chapter will use the Brand Module's service to implement the feature of creating a brand. In the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md), you'll expose an API route that allows admin users to create a brand, and you'll use this workflow in the route's implementation. - -Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). - -### Prerequisites - -- [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) - -*** - -## 1. Create createBrandStep - -A workflow consists of a series of steps, each step created in a TypeScript or JavaScript file under the `src/workflows` directory. A step is defined using `createStep` from the Workflows SDK - -The workflow you're creating in this guide has one step to create the brand. So, create the file `src/workflows/create-brand.ts` with the following content: - -![Directory structure in the Medusa project after adding the file for createBrandStep](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869184/Medusa%20Book/brand-workflow-dir-overview-1_fjvf5j.jpg) - -```ts title="src/workflows/create-brand.ts" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { BRAND_MODULE } from "../modules/brand" -import BrandModuleService from "../modules/brand/service" - -export type CreateBrandStepInput = { - name: string -} - -export const createBrandStep = createStep( - "create-brand-step", - async (input: CreateBrandStepInput, { container }) => { - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - - const brand = await brandModuleService.createBrands(input) - - return new StepResponse(brand, brand.id) - } -) -``` - -You create a `createBrandStep` using the `createStep` function. It accepts the step's unique name as a first parameter, and the step's function as a second parameter. - -The step function receives two parameters: input passed to the step when it's invoked, and an object of general context and configurations. This object has a `container` property, which is the Medusa container. - -The [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) is a registry of Framework and commerce tools accessible in your customizations, such as a workflow's step. The Medusa application registers the services of core and custom modules in the container, allowing you to resolve and use them. - -So, In the step function, you use the Medusa container to resolve the Brand Module's service and use its generated `createBrands` method, which accepts an object of brands to create. - -Learn more about the generated `create` method's usage in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/create/index.html.md). - -A step must return an instance of `StepResponse`. Its first parameter is the data returned by the step, and the second is the data passed to the compensation function, which you'll learn about next. - -### Add Compensation Function to Step - -You define for each step a compensation function that's executed when an error occurs in the workflow. The compensation function defines the logic to roll-back the changes made by the step. This ensures your data remains consistent if an error occurs, which is especially useful when you integrate third-party services. - -Learn more about the compensation function in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). - -To add a compensation function to the `createBrandStep`, pass it as a third parameter to `createStep`: - -```ts title="src/workflows/create-brand.ts" -export const createBrandStep = createStep( - // ... - async (id: string, { container }) => { - const brandModuleService: BrandModuleService = container.resolve( - BRAND_MODULE - ) - - await brandModuleService.deleteBrands(id) - } -) -``` - -The compensation function's first parameter is the brand's ID which you passed as a second parameter to the step function's returned `StepResponse`. It also accepts a context object with a `container` property as a second parameter, similar to the step function. - -In the compensation function, you resolve the Brand Module's service from the Medusa container, then use its generated `deleteBrands` method to delete the brand created by the step. This method accepts the ID of the brand to delete. - -Learn more about the generated `delete` method's usage in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/delete/index.html.md). - -So, if an error occurs during the workflow's execution, the brand that was created by the step is deleted to maintain data consistency. - -*** - -## 2. Create createBrandWorkflow - -You can now create the workflow that runs the `createBrandStep`. A workflow is created in a TypeScript or JavaScript file under the `src/workflows` directory.

This function accepts two parameters: the workflow's unique name, and the workflow's constructor function holding the workflow's implementation. - -The constructor function accepts the workflow's input as a parameter. In the function, you invoke the `createBrandStep` you created in the previous step to create a brand. - -A workflow must return an instance of `WorkflowResponse`.

So, to create a data model that represents a new `brand` table in the database, create the file `src/modules/brand/models/brand.ts` with the following content: + +![Directory structure in module after adding the brand data model](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868920/Medusa%20Book/brand-dir-overview-2_lexhdl.jpg) + +```ts title="src/modules/brand/models/brand.ts" +import { model } from "@medusajs/framework/utils" + +export const Brand = model.define("brand", { + id: model.id().primaryKey(), + name: model.text(), +}) +``` + +You create a `Brand` data model which has an `id` primary key property, and a `name` text property. + +You define the data model using the `define` method of the DML. It accepts two parameters: + +1. The first one is the name of the data model's table in the database. Use snake-case names. +2. The second is an object, which is the data model's schema. + +Learn about other property types in [this chapter](https://docs.medusajs.com/learn/fundamentals/data-models/properties/index.html.md). + +*** + +## 3. Create Module Service + +You perform database operations on your data models in a service, which is a class exported by the module and acts like an interface to its functionalities. + +In this step, you'll create the Brand Module's service that provides methods to manage the `Brand` data model. In the next chapters, you'll use this service when exposing custom features that involve managing brands. + +Learn more about services in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#2-create-service/index.html.md). + +You define a service in a `service.ts` or `service.js` file at the root of your module's directory. So, create the file `src/modules/brand/service.ts` with the following content: + +![Directory structure in module after adding the service](https://res.cloudinary.com/dza7lstvk/image/upload/v1732868984/Medusa%20Book/brand-dir-overview-3_jo7baj.jpg) + +```ts title="src/modules/brand/service.ts" highlights={serviceHighlights} +import { MedusaService } from "@medusajs/framework/utils" +import { Brand } from "./models/brand" + +class BrandModuleService extends MedusaService({ + Brand, +}) { + +} + +export default BrandModuleService +``` + +The `BrandModuleService` extends a class returned by `MedusaService` from the Modules SDK. This function generates a class with data-management methods for your module's data models. + +The `MedusaService` function receives an object of the module's data models as a parameter, and generates methods to manage those data models. So, the `BrandModuleService` now has methods like `createBrands` and `retrieveBrand` to manage the `Brand` data model. + +You'll use these methods in the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). + +Find a reference of all generated methods in [this guide](https://docs.medusajs.com/resources/service-factory-reference/index.html.md). + +*** + +## 4. Export Module Definition + +A module must export a definition that tells Medusa the name of the module and its main service. This definition is exported in an `index.ts` file at the module's root directory. + +So, to export the Brand Module's definition, create the file `src/modules/brand/index.ts` with the following content: + +![Directory structure in module after adding the definition file](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869045/Medusa%20Book/brand-dir-overview-4_nf8ymw.jpg) + +```ts title="src/modules/brand/index.ts" +import { Module } from "@medusajs/framework/utils" +import BrandModuleService from "./service" + +export const BRAND_MODULE = "brand" + +export default Module(BRAND_MODULE, { + service: BrandModuleService, +}) +``` + +You use `Module` from the Modules SDK to create the module's definition. It accepts two parameters: + +1. The module's name (`brand`). You'll use this name when you use this module in other customizations. +2. An object with a required property `service` indicating the module's main service. + +You export `BRAND_MODULE` to reference the module's name more reliably in other customizations. + +*** + +## 5. Add Module to Medusa's Configurations + +To start using your module, you must add it to Medusa's configurations in `medusa-config.ts`. + +The object passed to `defineConfig` in `medusa-config.ts` accepts a `modules` property, whose value is an array of modules to add to the application. So, add the following in `medusa-config.ts`: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/brand", + }, + ], +}) +``` + +The Brand Module is now added to your Medusa application. You'll start using it in the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/workflow/index.html.md). + +*** + +## 6. Generate and Run Migrations + +A migration is a TypeScript or JavaScript file that defines database changes made by a module. Migrations ensure that your module is re-usable and removes friction when working in a team, making it easy to reflect changes across team members' databases. + +Learn more about migrations in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules#5-generate-migrations/index.html.md). + +[Medusa's CLI tool](https://docs.medusajs.com/resources/medusa-cli/index.html.md) allows you to generate migration files for your module, then run those migrations to reflect the changes in the database. So, run the following commands in your Medusa application's directory: + +```bash +npx medusa db:generate brand +npx medusa db:migrate +``` + +The `db:generate` command accepts as an argument the name of the module to generate the migrations for, and the `db:migrate` command runs all migrations that haven't been run yet in the Medusa application. + +*** + +## Next Step: Create Brand Workflow + +The Brand Module now creates a `brand` table in the database and provides a class to manage its records. + +In the next chapter, you'll implement the functionality to create a brand in a workflow. You'll then use that workflow in a later chapter to expose an endpoint that allows admin users to create a brand. + + +# Guide: Create Brand Workflow + +This chapter builds on the work from the [previous chapter](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) where you created a Brand Module. + +After adding custom modules to your application, you build commerce features around them using workflows. A workflow is a series of queries and actions, called steps, that complete a task spanning across modules. You construct a workflow similar to a regular function, but it's a special function that allows you to define roll-back logic, retry configurations, and more advanced features. + +The workflow you'll create in this chapter will use the Brand Module's service to implement the feature of creating a brand. In the [next chapter](https://docs.medusajs.com/learn/customization/custom-features/api-route/index.html.md), you'll expose an API route that allows admin users to create a brand, and you'll use this workflow in the route's implementation. + +Learn more about workflows in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md). + +### Prerequisites + +- [Brand Module](https://docs.medusajs.com/learn/customization/custom-features/module/index.html.md) + +*** + +## 1. Create createBrandStep + +A workflow consists of a series of steps, each step created in a TypeScript or JavaScript file under the `src/workflows` directory. A step is defined using `createStep` from the Workflows SDK + +The workflow you're creating in this guide has one step to create the brand. So, create the file `src/workflows/create-brand.ts` with the following content: + +![Directory structure in the Medusa project after adding the file for createBrandStep](https://res.cloudinary.com/dza7lstvk/image/upload/v1732869184/Medusa%20Book/brand-workflow-dir-overview-1_fjvf5j.jpg) + +```ts title="src/workflows/create-brand.ts" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import { BRAND_MODULE } from "../modules/brand" +import BrandModuleService from "../modules/brand/service" + +export type CreateBrandStepInput = { + name: string +} + +export const createBrandStep = createStep( + "create-brand-step", + async (input: CreateBrandStepInput, { container }) => { + const brandModuleService: BrandModuleService = container.resolve( + BRAND_MODULE + ) + + const brand = await brandModuleService.createBrands(input) + + return new StepResponse(brand, brand.id) + } +) +``` + +You create a `createBrandStep` using the `createStep` function. It accepts the step's unique name as a first parameter, and the step's function as a second parameter. + +The step function receives two parameters: input passed to the step when it's invoked, and an object of general context and configurations. This object has a `container` property, which is the Medusa container. + +The [Medusa container](https://docs.medusajs.com/learn/fundamentals/medusa-container/index.html.md) is a registry of Framework and commerce tools accessible in your customizations, such as a workflow's step. The Medusa application registers the services of core and custom modules in the container, allowing you to resolve and use them. + +So, In the step function, you use the Medusa container to resolve the Brand Module's service and use its generated `createBrands` method, which accepts an object of brands to create. + +Learn more about the generated `create` method's usage in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/create/index.html.md). + +A step must return an instance of `StepResponse`. Its first parameter is the data returned by the step, and the second is the data passed to the compensation function, which you'll learn about next. + +### Add Compensation Function to Step + +You define for each step a compensation function that's executed when an error occurs in the workflow. The compensation function defines the logic to roll-back the changes made by the step. This ensures your data remains consistent if an error occurs, which is especially useful when you integrate third-party services. + +Learn more about the compensation function in [this chapter](https://docs.medusajs.com/learn/fundamentals/workflows/compensation-function/index.html.md). + +To add a compensation function to the `createBrandStep`, pass it as a third parameter to `createStep`: + +```ts title="src/workflows/create-brand.ts" +export const createBrandStep = createStep( + // ... + async (id: string, { container }) => { + const brandModuleService: BrandModuleService = container.resolve( + BRAND_MODULE + ) + + await brandModuleService.deleteBrands(id) + } +) +``` + +The compensation function's first parameter is the brand's ID which you passed as a second parameter to the step function's returned `StepResponse`. It also accepts a context object with a `container` property as a second parameter, similar to the step function. + +In the compensation function, you resolve the Brand Module's service from the Medusa container, then use its generated `deleteBrands` method to delete the brand created by the step. This method accepts the ID of the brand to delete. + +Learn more about the generated `delete` method's usage in [this reference](https://docs.medusajs.com/resources/service-factory-reference/methods/delete/index.html.md). + +So, if an error occurs during the workflow's execution, the brand that was created by the step is deleted to maintain data consistency. + +*** + +## 2. Create createBrandWorkflow + +You can now create the workflow that runs the `createBrandStep`. A workflow is created in a TypeScript or JavaScript file under the `src/workflows` directory. In the file, you use `createWorkflow` from the Workflows SDK to create the workflow. + +Add the following content in the same `src/workflows/create-brand.ts` file: + +```ts title="src/workflows/create-brand.ts" +// other imports... +import { + // ... + createWorkflow, + WorkflowResponse, +} from "@medusajs/framework/workflows-sdk" + +// ... + +type CreateBrandWorkflowInput = { + name: string +} + +export const createBrandWorkflow = createWorkflow( + "create-brand", + (input: CreateBrandWorkflowInput) => { + const brand = createBrandStep(input) + + return new WorkflowResponse(brand) + } +) +``` + +You create the `createBrandWorkflow` using the `createWorkflow` function. This function accepts two parameters: the workflow's unique name, and the workflow's constructor function holding the workflow's implementation. + +The constructor function accepts the workflow's input as a parameter. In the function, you invoke the `createBrandStep` you created in the previous step to create a brand. + +A workflow must return an instance of `WorkflowResponse`. It accepts as a parameter the data to return to the workflow's executor. + +*** + +## Next Steps: Expose Create Brand API Route + +You now have a `createBrandWorkflow` that you can execute to create a brand. + +In the next chapter, you'll add an API route that allows admin users to create a brand.

You set the `mappedBy` option to the many-to-many relation's name in the `Order` data model. +- `product`: A relation that indicates this model belongs to the `Product` data model. You set the `mappedBy` option to the many-to-many relation's name in the `Product` data model. +- `metadata`: An extra column to add to the pivot table of type `json`. You can add other columns as well to the model. + +*** + +## Set Relationship Name in the Other Model + +The relationship property methods accept as a second parameter an object of options. The `mappedBy` property defines the name of the relationship in the other data model. + +This is useful if the relationship property’s name is different from that of the associated data model. + +As seen in previous examples, the `mappedBy` option is required for the `belongsTo` method. + +For example: + +```ts highlights={relationNameHighlights} +import { model } from "@medusajs/framework/utils" + +const User = model.define("user", { + id: model.id().primaryKey(), + email: model.hasOne(() => Email, { + mappedBy: "owner", + }), +}) + +const Email = model.define("email", { + id: model.id().primaryKey(), + owner: model.belongsTo(() => User, { + mappedBy: "email", + }), +}) +``` + +In this example, you specify in the `User` data model’s relationship property that the name of the relationship in the `Email` data model is `owner`. + +*** + +## Cascades + +When an operation is performed on a data model, such as record deletion, the relationship cascade specifies what related data model records should be affected by it. + +For example, if a store is deleted, its products should also be deleted. + +The `cascades` method used on a data model configures which child records an operation is cascaded to. + +For example: + +```ts highlights={highlights} +import { model } from "@medusajs/framework/utils" + +const Store = model.define("store", { + id: model.id().primaryKey(), + products: model.hasMany(() => Product), +}) +.cascades({ + delete: ["products"], +}) + +const Product = model.define("product", { + id: model.id().primaryKey(), + store: model.belongsTo(() => Store, { + mappedBy: "products", + }), +}) +``` + +The `cascades` method accepts an object.

Publish Plugin Locally for Development and Testing - -Medusa's CLI tool provides commands to simplify developing and testing your plugin in a local Medusa application. You start by publishing your plugin in the local package registry, then install it in your Medusa application. You can then watch for changes in the plugin as you develop it. - -### Publish and Install Local Package - -### Prerequisites - -- [Medusa application installed.](https://docs.medusajs.com/learn/installation/index.html.md) - -The first time you create your plugin, you need to publish the package into a local package registry, then install it in your Medusa application. This is a one-time only process. - -To publish the plugin to the local registry, run the following command in your plugin project: - -```bash title="Plugin project" -npx medusa plugin:publish -``` - -This command uses [Yalc](https://github.com/wclr/yalc) under the hood to publish the plugin to a local package registry. The plugin is published locally under the name you specified in `package.json`. - -Next, navigate to your Medusa application: - -```bash title="Medusa application" -cd ~/path/to/medusa-app -``` - -Make sure to replace `~/path/to/medusa-app` with the path to your Medusa application. - -Then, if your project was created before v2.3.1 of Medusa, make sure to install `yalc` as a development dependency: - -```bash npm2yarn title="Medusa application" -npm install --save-dev yalc -``` - -After that, run the following Medusa CLI command to install the plugin: - -```bash title="Medusa application" -npx medusa plugin:add @myorg/plugin-name -``` - -Make sure to replace `@myorg/plugin-name` with the name of your plugin as specified in `package.json`. Your plugin will be installed from the local package registry into your Medusa application. - -### Register Plugin in Medusa Application - -After installing the plugin, you need to register it in your Medusa application in the configurations defined in `medusa-config.ts`. - -Add the plugin to the `plugins` array in the `medusa-config.ts` file: - -```ts title="medusa-config.ts" highlights={pluginHighlights} -module.exports = defineConfig({ - // ... - plugins: [ - { - resolve: "@myorg/plugin-name", - options: {}, - }, - ], -}) -``` - -The `plugins` configuration is an array of objects where each object has a `resolve` key whose value is the name of the plugin package. - -#### Pass Module Options through Plugin - -Each plugin configuration also accepts an `options` property, whose value is an object of options to pass to the plugin's modules. - -For example: - -```ts title="medusa-config.ts" highlights={pluginOptionsHighlight} -module.exports = defineConfig({ - // ... - plugins: [ - { - resolve: "@myorg/plugin-name", - options: { - apiKey: true, - }, - }, - ], -}) -``` - -The `options` property in the plugin configuration is passed to all modules in the plugin. Learn more about module options in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/options/index.html.md). - -### Watch Plugin Changes During Development - -While developing your plugin, you can watch for changes in the plugin and automatically update the plugin in the Medusa application using it. This is the only command you'll continuously need during your plugin development. - -To do that, run the following command in your plugin project: - -```bash title="Plugin project" -npx medusa plugin:develop -``` - -This command will: - -- Watch for changes in the plugin. Whenever a file is changed, the plugin is automatically built. -- Publish the plugin changes to the local package registry. This will automatically update the plugin in the Medusa application using it. You can also benefit from real-time HMR updates of admin extensions. - -### Start Medusa Application - -You can start your Medusa application's development server to test out your plugin: - -```bash npm2yarn title="Medusa application" -npm run dev -``` - -While your Medusa application is running and the plugin is being watched, you can test your plugin while developing it in the Medusa application. - -*** - -## 4. Create Customizations in the Plugin - -You can now build your plugin's customizations. The following guide explains how to build different customizations in your plugin. - -- [Create a module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md) -- [Create a module link](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) -- [Create a workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md) -- [Add a workflow hook](https://docs.medusajs.com/learn/fundamentals/workflows/add-workflow-hook/index.html.md) -- [Create an API route](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md) -- [Add a subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md) -- [Add a scheduled job](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs/index.html.md) -- [Add an admin widget](https://docs.medusajs.com/learn/fundamentals/admin/widgets/index.html.md) -- [Add an admin UI route](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md) - -While building those customizations, you can test them in your Medusa application by [watching the plugin changes](#watch-plugin-changes-during-development) and [starting the Medusa application](#start-medusa-application). - -### Generating Migrations for Modules - -During your development, you may need to generate migrations for modules in your plugin. To do that, first, add the following environment variables in your plugin project: - -```plain title="Plugin project" -DB_USERNAME=postgres -DB_PASSWORD=123... -DB_HOST=localhost -DB_PORT=5432 -DB_NAME=db_name -``` - -You can add these environment variables in a `.env` file in your plugin project.

Publish Plugin Locally for Development and Testing + +Medusa's CLI tool provides commands to simplify developing and testing your plugin in a local Medusa application. You start by publishing your plugin in the local package registry, then install it in your Medusa application. You can then watch for changes in the plugin as you develop it. + +### Publish and Install Local Package + +### Prerequisites + +- [Medusa application installed.](https://docs.medusajs.com/learn/installation/index.html.md) + +The first time you create your plugin, you need to publish the package into a local package registry, then install it in your Medusa application. This is a one-time only process. + +To publish the plugin to the local registry, run the following command in your plugin project: + +```bash title="Plugin project" +npx medusa plugin:publish +``` + +This command uses [Yalc](https://github.com/wclr/yalc) under the hood to publish the plugin to a local package registry. The plugin is published locally under the name you specified in `package.json`. + +Next, navigate to your Medusa application: + +```bash title="Medusa application" +cd ~/path/to/medusa-app +``` + +Make sure to replace `~/path/to/medusa-app` with the path to your Medusa application. + +Then, if your project was created before v2.3.1 of Medusa, make sure to install `yalc` as a development dependency: + +```bash npm2yarn title="Medusa application" +npm install --save-dev yalc +``` + +After that, run the following Medusa CLI command to install the plugin: + +```bash title="Medusa application" +npx medusa plugin:add @myorg/plugin-name +``` + +Make sure to replace `@myorg/plugin-name` with the name of your plugin as specified in `package.json`. Your plugin will be installed from the local package registry into your Medusa application. + +### Register Plugin in Medusa Application + +After installing the plugin, you need to register it in your Medusa application in the configurations defined in `medusa-config.ts`. + +Add the plugin to the `plugins` array in the `medusa-config.ts` file: + +```ts title="medusa-config.ts" highlights={pluginHighlights} +module.exports = defineConfig({ + // ... + plugins: [ + { + resolve: "@myorg/plugin-name", + options: {}, + }, + ], +}) +``` + +The `plugins` configuration is an array of objects where each object has a `resolve` key whose value is the name of the plugin package. + +#### Pass Module Options through Plugin + +Each plugin configuration also accepts an `options` property, whose value is an object of options to pass to the plugin's modules. + +For example: + +```ts title="medusa-config.ts" highlights={pluginOptionsHighlight} +module.exports = defineConfig({ + // ... + plugins: [ + { + resolve: "@myorg/plugin-name", + options: { + apiKey: true, + }, + }, + ], +}) +``` + +The `options` property in the plugin configuration is passed to all modules in the plugin. Learn more about module options in [this chapter](https://docs.medusajs.com/learn/fundamentals/modules/options/index.html.md). + +### Watch Plugin Changes During Development + +While developing your plugin, you can watch for changes in the plugin and automatically update the plugin in the Medusa application using it. This is the only command you'll continuously need during your plugin development. + +To do that, run the following command in your plugin project: + +```bash title="Plugin project" +npx medusa plugin:develop +``` + +This command will: + +- Watch for changes in the plugin. Whenever a file is changed, the plugin is automatically built. +- Publish the plugin changes to the local package registry. This will automatically update the plugin in the Medusa application using it. You can also benefit from real-time HMR updates of admin extensions. + +### Start Medusa Application + +You can start your Medusa application's development server to test out your plugin: + +```bash npm2yarn title="Medusa application" +npm run dev +``` + +While your Medusa application is running and the plugin is being watched, you can test your plugin while developing it in the Medusa application. + +*** + +## 4. Create Customizations in the Plugin + +You can now build your plugin's customizations. The following guide explains how to build different customizations in your plugin. + +- [Create a module](https://docs.medusajs.com/learn/fundamentals/modules/index.html.md) +- [Create a module link](https://docs.medusajs.com/learn/fundamentals/module-links/index.html.md) +- [Create a workflow](https://docs.medusajs.com/learn/fundamentals/workflows/index.html.md) +- [Add a workflow hook](https://docs.medusajs.com/learn/fundamentals/workflows/add-workflow-hook/index.html.md) +- [Create an API route](https://docs.medusajs.com/learn/fundamentals/api-routes/index.html.md) +- [Add a subscriber](https://docs.medusajs.com/learn/fundamentals/events-and-subscribers/index.html.md) +- [Add a scheduled job](https://docs.medusajs.com/learn/fundamentals/scheduled-jobs/index.html.md) +- [Add an admin widget](https://docs.medusajs.com/learn/fundamentals/admin/widgets/index.html.md) +- [Add an admin UI route](https://docs.medusajs.com/learn/fundamentals/admin/ui-routes/index.html.md) + +While building those customizations, you can test them in your Medusa application by [watching the plugin changes](#watch-plugin-changes-during-development) and [starting the Medusa application](#start-medusa-application). + +### Generating Migrations for Modules + +During your development, you may need to generate migrations for modules in your plugin. To do that, first, add the following environment variables in your plugin project: + +```plain title="Plugin project" +DB_USERNAME=postgres +DB_PASSWORD=123... +DB_HOST=localhost +DB_PORT=5432 +DB_NAME=db_name +``` + +You can add these environment variables in a `.env` file in your plugin project. The variables are: + +- `DB_USERNAME`: The username of the PostgreSQL user to connect to the database. +- `DB_PASSWORD`: The password of the PostgreSQL user to connect to the database. +- `DB_HOST`: The host of the PostgreSQL database. Typically, it's `localhost` if you're running the database locally. +- `DB_PORT`: The port of the PostgreSQL database. Typically, it's `5432` if you're running the database locally. +- `DB_NAME`: The name of the PostgreSQL database to connect to. + +Then, run the following command in your plugin project to generate migrations for the modules in your plugin: + +```bash title="Plugin project" +npx medusa plugin:db:generate +``` + +This command generates migrations for all modules in the plugin. + +Finally, run these migrations on the Medusa application that the plugin is installed in using the `db:migrate` command: + +```bash title="Medusa application" +npx medusa db:migrate +``` + +The migrations in your application, including your plugin, will run and update the database. + +### Importing Module Resources + +In the [Prepare Plugin](#2-prepare-plugin) section, you learned about [exported resources](#package-exports) in your plugin. + +These exports allow you to import your plugin resources in your Medusa application, including workflows, links and modules. + +For example, to import the plugin's workflow in your Medusa application: + +`@myorg/plugin-name` is the plugin package's name. + +```ts +import { Workflow1, Workflow2 } from "@myorg/plugin-name/workflows" +import BlogModule from "@myorg/plugin-name/modules/blog" +// import other files created in plugin like ./src/types/blog.ts +import BlogType from "@myorg/plugin-name/types/blog" +``` + +### Create Module Providers + +The [exported resources](#package-exports) also allow you to import module providers in your plugin and register them in the Medusa application's configuration. A module provider is a module that provides the underlying logic or integration related to a commerce or Infrastructure Module. + +For example, assuming your plugin has a [Notification Module Provider](https://docs.medusajs.com/resources/infrastructure-modules/notification/index.html.md) called `my-notification`, you can register it in your Medusa application's configuration like this: + +`@myorg/plugin-name` is the plugin package's name. + +```ts highlights={[["9"]]} title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "@medusajs/medusa/notification", + options: { + providers: [ + { + resolve: "@myorg/plugin-name/providers/my-notification", + id: "my-notification", + options: { + channels: ["email"], + // provider options... + }, + }, + ], + }, + }, + ], +}) +``` + +You pass to `resolve` the path to the provider relative to the plugin package. So, in this example, the `my-notification` provider is located in `./src/providers/my-notification/index.ts` of the plugin. + +To learn how to create module providers, refer to the following guides: + +- [File Module Provider](https://docs.medusajs.com/resources/references/file-provider-module/index.html.md) +- [Notification Module Provider](https://docs.medusajs.com/resources/references/notification-provider-module/index.html.md) +- [Auth Module Provider](https://docs.medusajs.com/resources/references/auth/provider/index.html.md) +- [Payment Module Provider](https://docs.medusajs.com/resources/references/payment/provider/index.html.md) +- [Fulfillment Module Provider](https://docs.medusajs.com/resources/references/fulfillment/provider/index.html.md) +- [Tax Module Provider](https://docs.medusajs.com/resources/references/tax/provider/index.html.md) + +*** + +## 5.

You will be helping the open source community and other developers interested in learning more about Medusa and using it. - -This guide is specific to contributing to the documentation. If you’re interested in contributing to Medusa’s codebase, check out the [contributing guidelines in the Medusa GitHub repository](https://github.com/medusajs/medusa/blob/develop/CONTRIBUTING.md). - -## What Can You Contribute? - -You can contribute to the Medusa documentation in the following ways: - -- Fixes to existing content. This includes small fixes like typos, or adding missing information. -- Additions to the documentation. If you think a documentation page can be useful to other developers, you can contribute by adding it. - - Make sure to open an issue first in the [medusa repository](https://github.com/medusajs/medusa) to confirm that you can add that documentation page. -- Fixes to UI components and tooling. If you find a bug while browsing the documentation, you can contribute by fixing it. - -*** - -## Documentation Workspace - -Medusa's documentation projects are all part of the documentation yarn workspace, which you can find in the [medusa repository](https://github.com/medusajs/medusa) under the `www` directory. - -The workspace has the following two directories: - -- `apps`: this directory holds the different documentation websites and projects. - - `book`: includes the codebase for the [main Medusa documentation](https://docs.medusajs.com//index.html.md). It's built with [Next.js 15](https://nextjs.org/). - - `resources`: includes the codebase for the resources documentation, which powers different sections of the docs such as the [Integrations](https://docs.medusajs.com/resources/integrations/index.html.md) or [How-to & Tutorials](https://docs.medusajs.com/resources/how-to-tutorials/index.html.md) sections. It's built with [Next.js 15](https://nextjs.org/). - - `api-reference`: includes the codebase for the API reference website. It's built with [Next.js 15](https://nextjs.org/). - - `ui`: includes the codebase for the Medusa UI documentation website. It's built with [Next.js 15](https://nextjs.org/). -- `packages`: this directory holds the shared packages and components necessary for the development of the projects in the `apps` directory. - - `docs-ui` includes the shared React components between the different apps. - - `remark-rehype-plugins` includes Remark and Rehype plugins used by the documentation projects. - -*** - -## Documentation Content - -All documentation projects are built with Next.js. The content is writtin in MDX files. - -### Medusa Main Docs Content - -The content of the Medusa main docs are under the `www/apps/book/app` directory. - -### Medusa Resources Content - -The content of all pages under the `/resources` path are under the `www/apps/resources/app` directory. - -Documentation pages under the `www/apps/resources/references` directory are generated automatically from the source code under the `packages/medusa` directory. So, you can't directly make changes to them. Instead, you'll have to make changes to the comments in the original source code. - -### API Reference - -The API reference's content is split into two types: - -1. Static content, which are the content related to getting started, expanding fields, and more. These are located in the `www/apps/api-reference/markdown` directory. They are MDX files. -2. OpenAPI specs that are shown to developers when checking the reference of an API Route. These are generated from OpenApi Spec comments, which are under the `www/utils/generated/oas-output` directory. - -### Medusa UI Documentation - -The content of the Medusa UI documentation are located under the `www/apps/ui/src/content/docs` directory. They are MDX files. - -The UI documentation also shows code examples, which are under the `www/apps/ui/src/examples` directory. - -The UI component props are generated from the source code and placed into the `www/apps/ui/src/specs` directory. To contribute to these props and their comments, check the comments in the source code under the `packages/design-system/ui` directory. - -*** - -## Style Guide - -When you contribute to the documentation content, make sure to follow the [documentation style guide](https://www.notion.so/Style-Guide-Docs-fad86dd1c5f84b48b145e959f36628e0). - -*** - -## How to Contribute - -If you’re fixing errors in an existing documentation page, you can scroll down to the end of the page and click on the “Edit this page” link. You’ll be redirected to the GitHub edit form of that page and you can make edits directly and submit a pull request (PR). - -If you’re adding a new page or contributing to the codebase, fork the repository, create a new branch, and make all changes necessary in your repository. Then, once you’re done, create a PR in the Medusa repository. - -### Base Branch - -When you make an edit to an existing documentation page or fork the repository to make changes to the documentation, create a new branch. - -Documentation contributions always use `develop` as the base branch. Make sure to also open your PR against the `develop` branch. - -### Branch Name - -Make sure that the branch name starts with `docs/`. For example, `docs/fix-services`. Vercel deployed previews are only triggered for branches starting with `docs/`. - -### Pull Request Conventions - -When you create a pull request, prefix the title with `docs:` or `docs(PROJECT_NAME):`, where `PROJECT_NAME` is the name of the documentation project this pull request pertains to. For example, `docs(ui): fix titles`. - -In the body of the PR, explain clearly what the PR does. If the PR solves an issue, use [closing keywords](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword) with the issue number. For example, “Closes #1333”. - -*** - -## Images - -If you are adding images to a documentation page, you can host the image on [Imgur](https://imgur.com) for free to include it in the PR. Our team will later upload it to our image hosting. - -*** - -## NPM and Yarn Code Blocks - -If you’re adding code blocks that use NPM and Yarn, you must add the `npm2yarn` meta field. - -For example: - -````md -```bash npm2yarn -npm run start -``` -```` - -The code snippet must be written using NPM. - -### Global Option - -When a command uses the global option `-g`, add it at the end of the NPM command to ensure that it’s transformed to a Yarn command properly. For example: - -```bash npm2yarn -npm install @medusajs/cli -g -``` - -*** - -## Linting with Vale - -Medusa uses [Vale](https://vale.sh/) to lint documentation pages and perform checks on incoming PRs into the repository. - -### Result of Vale PR Checks - -You can check the result of running the "lint" action on your PR by clicking the Details link next to it.

The test pases if the workflow returns the string `"Hello, World!"`. - -### Jest Timeout - -Since your tests connect to the database and perform actions that require more time than the typical tests, make sure to increase the timeout in your test: - -```ts title="integration-tests/http/custom-routes.spec.ts" -// in your test's file -jest.setTimeout(60 * 1000) -``` - -*** - -## Run Test - -Run the following command to run your tests: - -```bash npm2yarn -npm run test:integration -``` - -If you don't have a `test:integration` script in `package.json`, refer to the [Medusa Testing Tools chapter](https://docs.medusajs.com/learn/debugging-and-testing/testing-tools#add-test-commands/index.html.md). - -This runs your Medusa application and runs the tests available under the `integrations/http` directory. - -*** - -## Test That a Workflow Throws an Error - -You might want to test that a workflow throws an error in certain cases. To test this: - -- Disable the `throwOnError` option when executing the workflow. -- Use the returned `errors` property to check what errors were thrown. - -For example, if you have a step that throws this error: - -```ts title="src/workflows/hello-world.ts" -import { MedusaError } from "@medusajs/framework/utils" -import { createStep } from "@medusajs/framework/workflows-sdk" - -const step1 = createStep("step-1", () => { - throw new MedusaError(MedusaError.Types.NOT_FOUND, "Item doesn't exist") -}) -``` - -You can write the following test to ensure that the workflow throws that error: - -```ts title="integration-tests/http/workflow.spec.ts" -import { medusaIntegrationTestRunner } from "@medusajs/test-utils" -import { helloWorldWorkflow } from "../../src/workflows/hello-world" - -medusaIntegrationTestRunner({ - testSuite: ({ getContainer }) => { - describe("Test hello-world workflow", () => { - it("returns message", async () => { - const { errors } = await helloWorldWorkflow(getContainer()) - .run({ - throwOnError: false, - }) - - expect(errors.length).toBeGreaterThan(0) - expect(errors[0].error.message).toBe("Item doesn't exist") - }) - }) - }, -}) - -jest.setTimeout(60 * 1000) -``` - -The `errors` property contains an array of errors thrown during the execution of the workflow. Each error item has an `error` object, being the error thrown. - -If you threw a `MedusaError`, then you can check the error message in `errors[0].error.message`. - - # Example: Write Integration Tests for API Routes In this chapter, you'll learn how to write integration tests for API routes using [medusaIntegrationTestRunner](https://docs.medusajs.com/learn/debugging-and-testing/testing-tools/integration-tests/index.html.md) from Medusa's Testing Framework. @@ -17978,6 +17489,495 @@ const response = await api.post(`/custom`, form, { ``` +# Docs Contribution Guidelines + +Thank you for your interest in contributing to the documentation!

In this documentation, you'll learn how to contribute to the community by translating the Medusa Admin to a language you're fluent in. + +{/* vale docs.We = NO */} + +You can contribute either by translating the admin to a new language, or fixing translations for existing languages. As we can't validate every language's translations, some translations may be incorrect. Your contribution is welcome to fix any translation errors you find. + +{/* vale docs.We = YES */} + +Check out the translated languages either in the admin dashboard's settings or on [GitHub](https://github.com/medusajs/medusa/blob/develop/packages/admin/dashboard/src/i18n/languages.ts). + +*** + +## How to Contribute Translation + +1. Clone the [Medusa monorepository](https://github.com/medusajs/medusa) to your local machine: + +```bash +git clone https://github.com/medusajs/medusa.git +``` + +If you already have it cloned, make sure to pull the latest changes from the `develop` branch. + +2. Install the monorepository's dependencies. Since it's a Yarn workspace, it's highly recommended to use yarn: + +```bash +yarn install +``` + +3. Create a branch that you'll use to open the pull request later: + +```bash +git checkout -b feat/translate- +``` + +Where `` is your language name. For example, `feat/translate-da`. + +4. Translation files are under `packages/admin/dashboard/src/i18n/translations` as JSON files whose names are the ISO-2 name of the language. + - If you're adding a new language, copy the file `packages/admin/dashboard/src/i18n/translations/en.json` and paste it with the ISO-2 name for your language. For example, if you're adding Danish translations, copy the `en.json` file and paste it as `packages/admin/dashboard/src/i18n/translations/de.json`. + - If you're fixing a translation, find the JSON file of the language under `packages/admin/dashboard/src/i18n/translations`. + +5. Start translating the keys in the JSON file (or updating the targeted ones). All keys in the JSON file must be translated, and your PR tests will fail otherwise. + - You can check whether the JSON file is valid by running the following command in `packages/admin/dashboard`, replacing `da.json` with the JSON file's name: + +```bash title="packages/admin/dashboard" +yarn i18n:validate da.json +``` + +6. After finishing the translation, if you're adding a new language, import its JSON file in `packages/admin/dashboard/src/i18n/translations/index.ts` and add it to the exported object: + +```ts title="packages/admin/dashboard/src/i18n/translations/index.ts" highlights={[["2"], ["6"], ["7"], ["8"]]} +// other imports... +import da from "./da.json" + +export default { + // other languages... + da: { + translation: da, + }, +} +``` + +The language's key in the object is the ISO-2 name of the language. + +7. If you're adding a new language, add it to the file `packages/admin/dashboard/src/i18n/languages.ts`: + +```ts title="packages/admin/dashboard/src/i18n/languages.ts" highlights={languageHighlights} +import { da } from "date-fns/locale" +// other imports... + +export const languages: Language[] = [ + // other languages... + { + code: "da", + display_name: "Danish", + ltr: true, + date_locale: da, + }, +] +``` + +`languages` is an array having the following properties: + +- `code`: The ISO-2 name of the language. For example, `da` for Danish. +- `display_name`: The language's name to be displayed in the admin. +- `ltr`: Whether the language supports a left-to-right layout. For example, set this to `false` for languages like Arabic. +- `date_locale`: An instance of the locale imported from the [date-fns/locale](https://date-fns.org/) package. + +8.

The test pases if the workflow returns the string `"Hello, World!"`. + +### Jest Timeout + +Since your tests connect to the database and perform actions that require more time than the typical tests, make sure to increase the timeout in your test: + +```ts title="integration-tests/http/custom-routes.spec.ts" +// in your test's file +jest.setTimeout(60 * 1000) +``` + +*** + +## Run Test + +Run the following command to run your tests: + +```bash npm2yarn +npm run test:integration +``` + +If you don't have a `test:integration` script in `package.json`, refer to the [Medusa Testing Tools chapter](https://docs.medusajs.com/learn/debugging-and-testing/testing-tools#add-test-commands/index.html.md). + +This runs your Medusa application and runs the tests available under the `integrations/http` directory. + +*** + +## Test That a Workflow Throws an Error + +You might want to test that a workflow throws an error in certain cases. To test this: + +- Disable the `throwOnError` option when executing the workflow. +- Use the returned `errors` property to check what errors were thrown. + +For example, if you have a step that throws this error: + +```ts title="src/workflows/hello-world.ts" +import { MedusaError } from "@medusajs/framework/utils" +import { createStep } from "@medusajs/framework/workflows-sdk" + +const step1 = createStep("step-1", () => { + throw new MedusaError(MedusaError.Types.NOT_FOUND, "Item doesn't exist") +}) +``` + +You can write the following test to ensure that the workflow throws that error: + +```ts title="integration-tests/http/workflow.spec.ts" +import { medusaIntegrationTestRunner } from "@medusajs/test-utils" +import { helloWorldWorkflow } from "../../src/workflows/hello-world" + +medusaIntegrationTestRunner({ + testSuite: ({ getContainer }) => { + describe("Test hello-world workflow", () => { + it("returns message", async () => { + const { errors } = await helloWorldWorkflow(getContainer()) + .run({ + throwOnError: false, + }) + + expect(errors.length).toBeGreaterThan(0) + expect(errors[0].error.message).toBe("Item doesn't exist") + }) + }) + }, +}) + +jest.setTimeout(60 * 1000) +``` + +The `errors` property contains an array of errors thrown during the execution of the workflow. Each error item has an `error` object, being the error thrown. + +If you threw a `MedusaError`, then you can check the error message in `errors[0].error.message`. + + # Example: Integration Tests for a Module In this chapter, find an example of writing an integration test for a module using [moduleIntegrationTestRunner](https://docs.medusajs.com/learn/debugging-and-testing/testing-tools/modules-tests/index.html.md) from Medusa's Testing Framework. @@ -18228,6 +18228,445 @@ Learn more about workflows in [this documentation](https://docs.medusajs.com/doc *** +# Customer Module + +In this section of the documentation, you will find resources to learn more about the Customer Module and how to use it in your application. + +Refer to the [Medusa Admin User Guide](https://docs.medusajs.com/user-guide/customers/index.html.md) to learn how to manage customers and groups using the dashboard. + +Medusa has customer related features available out-of-the-box through the Customer Module.

This field indicates whether you'll manage the inventory quantity of the product variant in the Medusa application. You can also keep `manage_inventory` disabled if you manage the product's inventory in an external system, such as an ERP. - -The Product Module doesn't provide inventory-management features. Instead, the Medusa application uses the [Inventory Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/index.html.md) to manage inventory for products and variants. When `manage_inventory` is disabled, the Medusa application always considers the product variant to be in stock. This is useful if your product's variants aren't items that can be stocked, such as digital products, or they don't have a limited stock quantity. - -When `manage_inventory` is enabled, the Medusa application tracks the inventory of the product variant using the [Inventory Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/index.html.md). For example, when a customer purchases a product variant, the Medusa application decrements the stocked quantity of the product variant. - -*** - -## How the Medusa Application Manages Inventory - -When a product variant has `manage_inventory` enabled, the Medusa application creates an inventory item using the [Inventory Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/index.html.md) and links it to the product variant. - -![Diagram showcasing the link between a product variant and its inventory item](https://res.cloudinary.com/dza7lstvk/image/upload/v1709652779/Medusa%20Resources/product-inventory_kmjnud.jpg) - -The inventory item has one or more locations, called inventory levels, that represent the stock quantity of the product variant at a specific location.

This API key specifies the sales channels, available through the [Sales Channel Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/sales-channel/index.html.md), of the storefront. - -The Medusa application links sales channels to stock locations, indicating the locations available for a specific sales channel. So, all inventory-related operations are scoped by the sales channel and its associated stock locations. - -For example, the availability of a product variant is determined by the `stocked_quantity` of its inventory level at the stock location linked to the storefront's sales channel. - -![Diagram showcasing the overall relations between inventory, stock location, and sales channel concepts](https://res.cloudinary.com/dza7lstvk/image/upload/v1738582163/Medusa%20Resources/inventory-stock-sales_fknoxw.jpg) - -*** - -## Variant Back Orders - -Product variants have an `allow_backorder` field that's disabled by default. When enabled, the Medusa application allows customers to purchase the product variant even when it's out of stock. Use this when your product variant is available through on-demand or pre-order purchase. - -You can also allow customers to subscribe to restock notifications of a product variant as explained in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/recipes/commerce-automation/restock-notification/index.html.md). - -*** - -## Additional Resources - -The following guides provide more details on inventory management in the Medusa application: - -- [Inventory Kits in the Inventory Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/inventory-kit/index.html.md): Learn how you can implement bundled or multi-part products through the Inventory Module. -- [Configure Selling Products](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/product/selling-products/index.html.md): Learn how to use inventory management to support different use cases when selling products. -- [Inventory in Flows](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/inventory-in-flows/index.html.md): Learn how Medusa utilizes inventory management in different flows. -- [Storefront guide: how to retrieve a product variant's inventory details](https://docs.medusajs.com/resources/storefront-development/products/inventory/index.html.md). - - -# Configure Selling Products - -In this guide, you'll learn how to set up and configure your products based on their shipping and inventory requirements, the product type, how you want to sell them, or your commerce ecosystem. - -The concepts in this guide are applicable starting from Medusa v2.5.1. - -## Scenario - -Businesses can have different selling requirements: - -1. They may sell physical or digital items. -2. They may sell items that don't require shipping or inventory management, such as selling digital products, services, or booking appointments. -3. They may sell items whose inventory is managed by an external system, such as an ERP. - -Medusa supports these different selling requirements by allowing you to configure shipping and inventory requirements for products and their variants. This guide explains how these configurations work, then provides examples of setting up different use cases. - -*** - -## Configuring Shipping Requirements - -The Medusa application defines a link between the `Product` data model and a [ShippingProfile](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/fulfillment/concepts#shipping-profile/index.html.md) in the [Fulfillment Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/fulfillment/index.html.md), allowing you to associate a product with a shipping profile. - -When a product is associated with a shipping profile, its variants require shipping and fulfillment when purchased. This is useful for physical products or digital products that require custom fulfillment. - -If a product doesn't have an associated shipping profile, its variants don't require shipping and fulfillment when purchased. This is useful for digital products, for example, that don't require shipping. - -### Overriding Shipping Requirements for Variants - -A product variant whose inventory is managed by Medusa (its `manage_inventory` property is enabled) has an [inventory item](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/concepts#inventoryitem/index.html.md). The inventory item has a `requires_shipping` property that can be used to override its shipping requirement. This is useful if the product has an associated shipping profile but you want to disable shipping for a specific variant, or vice versa. - -Learn more about product variant's inventory in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/product/variant-inventory/index.html.md). - -When a product variant is purchased, the Medusa application decides whether the purchased item requires shipping in the following order: - -1. The product variant has an inventory item. In this case, the Medusa application uses the inventory item's `requires_shipping` property to determine if the item requires shipping. -2. If the product variant doesn't have an inventory item, the Medusa application checks whether the product has an associated shipping profile to determine if the item requires shipping. - -*** - -## Use Case Examples - -By combining configurations of shipment requirements and inventory management, you can set up your products to support your use case: - -|Use Case|Configurations|Example| -|---|---|---|---|---| -|Item that's shipped on purchase, and its variant inventory is managed by the Medusa application.||Any stock-kept item (clothing, for example), whose inventory is managed in the Medusa application.| -|Item that's shipped on purchase, but its variant inventory is managed externally (not by Medusa) or it has infinite stock.||Any stock-kept item (clothing, for example), whose inventory is managed in an ERP or has infinite stock.| -|Item that's not shipped on purchase, but its variant inventory is managed by Medusa.||Digital products, such as licenses, that don't require shipping but have a limited quantity.| -|Item that doesn't require shipping and its variant inventory isn't managed by Medusa.||| - - # Pricing Concepts In this document, you’ll learn about the main concepts in the Pricing Module. @@ -27259,6 +26696,254 @@ In this example, the price is only applied if a cart's customer belongs to the c These same rules apply to product variant prices as well, or any other resource that has a price. +# Tax-Inclusive Pricing + +In this document, you’ll learn about tax-inclusive pricing and how it's used when calculating prices. + +## What is Tax-Inclusive Pricing? + +A tax-inclusive price is a price of a resource that includes taxes.

It creates a read-only link between the `InventoryLevel` and `StockLocation` data models so that it can retrieve the stock location of an inventory level. + +![Diagram showcasing the read-only link between an inventory level and a stock location](https://res.cloudinary.com/dza7lstvk/image/upload/v1738582163/Medusa%20Resources/inventory-level-stock_amxfg5.jpg) + +Learn more about the Stock Location Module in the [Stock Location Module's documentation](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/stock-location/concepts/index.html.md). + +### Product Inventory in Storefronts + +When a storefront sends a request to the Medusa application, it must always pass a [publishable API key](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/sales-channel/publishable-api-keys/index.html.md) in the request header. This API key specifies the sales channels, available through the [Sales Channel Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/sales-channel/index.html.md), of the storefront. + +The Medusa application links sales channels to stock locations, indicating the locations available for a specific sales channel. So, all inventory-related operations are scoped by the sales channel and its associated stock locations. + +For example, the availability of a product variant is determined by the `stocked_quantity` of its inventory level at the stock location linked to the storefront's sales channel. + +![Diagram showcasing the overall relations between inventory, stock location, and sales channel concepts](https://res.cloudinary.com/dza7lstvk/image/upload/v1738582163/Medusa%20Resources/inventory-stock-sales_fknoxw.jpg) + +*** + +## Variant Back Orders + +Product variants have an `allow_backorder` field that's disabled by default. When enabled, the Medusa application allows customers to purchase the product variant even when it's out of stock. Use this when your product variant is available through on-demand or pre-order purchase. + +You can also allow customers to subscribe to restock notifications of a product variant as explained in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/recipes/commerce-automation/restock-notification/index.html.md). + +*** + +## Additional Resources + +The following guides provide more details on inventory management in the Medusa application: + +- [Inventory Kits in the Inventory Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/inventory-kit/index.html.md): Learn how you can implement bundled or multi-part products through the Inventory Module. +- [Configure Selling Products](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/product/selling-products/index.html.md): Learn how to use inventory management to support different use cases when selling products. +- [Inventory in Flows](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/inventory/inventory-in-flows/index.html.md): Learn how Medusa utilizes inventory management in different flows. +- [Storefront guide: how to retrieve a product variant's inventory details](https://docs.medusajs.com/resources/storefront-development/products/inventory/index.html.md). + # Links between Sales Channel Module and Other Modules @@ -28597,6 +28702,161 @@ const { data: stores } = useQueryGraphStep({ ``` +# User Creation Flows + +In this document, learn the different ways to create a user using the User Module. + +Refer to this [Medusa Admin User Guide](https://docs.medusajs.com/user-guide/settings/users/index.html.md) to learn how to manage users using the dashboard. + +## Straightforward User Creation + +To create a user, use the [create method of the User Module’s main service](https://docs.medusajs.com/references/user/create/index.html.md): + +```ts +const user = await userModuleService.createUsers({ + email: "user@example.com", +}) +``` + +You can pair this with the Auth Module to allow the user to authenticate, as explained in a [later section](#create-identity-with-the-auth-module). + +*** + +## Invite Users + +To create a user, you can create an invite for them using the [createInvites method](https://docs.medusajs.com/references/user/createInvites/index.html.md) of the User Module's main service: + +```ts +const invite = await userModuleService.createInvites({ + email: "user@example.com", +}) +``` + +Later, you can accept the invite and create a new user for them: + +```ts +const invite = + await userModuleService.validateInviteToken("secret_123") + +await userModuleService.updateInvites({ + id: invite.id, + accepted: true, +}) + +const user = await userModuleService.createUsers({ + email: invite.email, +}) +``` + +### Invite Expiry + +An invite has an expiry date.

The Medusa application's commerce features are built around [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md) which are available out-of-the-box. These features include managing carts and adding line items to them. - -By default, you can add product variants to the cart, where the price of its associated line item is based on the product variant's price. However, you can build customizations to add line items with custom prices to the cart. This is useful when integrating an Enterprise Resource Planning (ERP), Product Information Management (PIM), or other third-party services that provide real-time prices for your products. - -To showcase how to add line items with custom prices to the cart, this guide uses [GoldAPI.io](https://www.goldapi.io) as an example of a third-party system that you can integrate for real-time prices. You can follow the same approach for other third-party integrations that provide custom pricing. - -You can follow this guide whether you're new to Medusa or an advanced Medusa developer. - -### Summary - -This guide will teach you how to: - -- Install and set up Medusa. -- Integrate the third-party service [GoldAPI.io](https://www.goldapi.io) that retrieves real-time prices for metals like Gold and Silver. -- Add an API route to add a product variant that has metals, such as a gold ring, to the cart with the real-time price retrieved from the third-party service. - -![Diagram showcasing overview of implementation for adding an item to cart from storefront.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738920014/Medusa%20Resources/custom-line-item-3_zu3qh2.jpg) - -- [Custom Item Price Repository](https://github.com/medusajs/examples/tree/main/custom-item-price): Find the full code for this guide in this repository. -- [OpenApi Specs for Postman](https://res.cloudinary.com/dza7lstvk/raw/upload/v1738246728/OpenApi/Custom_Item_Price_gdfnl3.yaml): Import this OpenApi Specs file into tools like Postman. - -*** - -## Step 1: Install a Medusa Application - -### Prerequisites - -- [Node.js v20+](https://nodejs.org/en/download) -- [Git CLI tool](https://git-scm.com/downloads) -- [PostgreSQL](https://www.postgresql.org/download/) - -Start by installing the Medusa application on your machine with the following command: - -```bash -npx create-medusa-app@latest -``` - -You'll first be asked for the project's name. You can also optionally choose to install the [Next.js starter storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md). - -Afterwards, the installation process will start, which will install the Medusa application in a directory with your project's name. If you chose to install the Next.js starter, it'll be installed in a separate directory with the `{project-name}-storefront` name. - -The Medusa application is composed of a headless Node.js server and an admin dashboard. The storefront is installed or custom-built separately and connects to the Medusa application through its REST endpoints, called [API routes](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). Learn more about Medusa's architecture in [this documentation](https://docs.medusajs.com/docs/learn/introduction/architecture/index.html.md). - -Once the installation finishes successfully, the Medusa Admin dashboard will open with a form to create a new user. Enter the user's credentials and submit the form. Afterwards, you can log in with the new user and explore the dashboard. - -Check out the [troubleshooting guides](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/troubleshooting/create-medusa-app-errors/index.html.md) for help. - -*** - -## Step 2: Integrate GoldAPI.io - -### Prerequisites - -- [GoldAPI.io Account. You can create a free account.](https://www.goldapi.io) - -To integrate third-party services into Medusa, you create a custom module. A module is a reusable package with functionalities related to a single feature or domain. Medusa integrates the module into your application without implications or side effects on your setup. - -In this step, you'll create a Metal Price Module that uses the GoldAPI.io service to retrieve real-time prices for metals like Gold and Silver. You'll use this module later to retrieve the real-time price of a product variant based on the metals in it, and add it to the cart with that custom price. - -Learn more about modules in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md). - -### Create Module Directory - -A module is created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/metal-prices`. - -![Diagram showcasing the module directory to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1738247192/Medusa%20Resources/custom-item-price-1_q16evr.jpg) - -### Create Module's Service - -You define a module's functionalities in a service. A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, which is useful if your module defines tables in the database, or connect to a third-party service. - -In this section, you'll create the Metal Prices Module's service that connects to the GoldAPI.io service to retrieve real-time prices for metals. - -Start by creating the file `src/modules/metal-prices/service.ts` with the following content: - -![Diagram showcasing the service file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1738247303/Medusa%20Resources/custom-item-price-2_eaefis.jpg) - -```ts title="src/modules/metal-prices/service.ts" -type Options = { - accessToken: string - sandbox?: boolean -} - -export default class MetalPricesModuleService { - protected options_: Options - - constructor({}, options: Options) { - this.options_ = options - } -} -``` - -A module can accept options that are passed to its service. You define an `Options` type that indicates the options the module accepts. It accepts two options: - -- `accessToken`: The access token for the GoldAPI.io service. -- `sandbox`: A boolean that indicates whether to simulate sending requests to the GoldAPI.io service. This is useful when running in a test environment. - -The service's constructor receives the module's options as a second parameter. You store the options in the service's `options_` property. - -A module has a container of Medusa Framework tools and local resources in the module that you can access in the service constructor's first parameter. Learn more in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md). - -#### Add Method to Retrieve Metal Prices - -Next, you'll add the method to retrieve the metal prices from the third-party service. - -First, add the following types at the beginning of `src/modules/metal-prices/service.ts`: - -```ts title="src/modules/metal-prices/service.ts" -export enum MetalSymbols { - Gold = "XAU", - Silver = "XAG", - Platinum = "XPT", - Palladium = "XPD" -} - -export type PriceResponse = { - metal: MetalSymbols - currency: string - exchange: string - symbol: string - price: number - [key: string]: unknown -} - -``` - -The `MetalSymbols` enum defines the symbols for metals like Gold, Silver, Platinum, and Palladium. The `PriceResponse` type defines the structure of the response from the GoldAPI.io's endpoint. - -Next, add the method `getMetalPrices` to the `MetalPricesModuleService` class: - -```ts title="src/modules/metal-prices/service.ts" -import { MedusaError } from "@medusajs/framework/utils" - -// ... - -export default class MetalPricesModuleService { - // ... - async getMetalPrice( - symbol: MetalSymbols, - currency: string - ): Promise { - const upperCaseSymbol = symbol.toUpperCase() - const upperCaseCurrency = currency.toUpperCase() - - return fetch(`https://www.goldapi.io/api/${upperCaseSymbol}/${upperCaseCurrency}`, { - headers: { - "x-access-token": this.options_.accessToken, - "Content-Type": "application/json", - }, - redirect: "follow", - }).then((response) => response.json()) - .then((response) => { - if (response.error) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - response.error - ) - } - - return response - }) - } -} -``` - -The `getMetalPrice` method accepts the metal symbol and currency as parameters. You send a request to GoldAPI.io's `/api/{symbol}/{currency}` endpoint to retrieve the metal's price, also passing the access token in the request's headers. - -If the response contains an error, you throw a `MedusaError` with the error message. Otherwise, you return the response, which is of type `PriceResponse`. - -#### Add Helper Methods - -You'll also add two helper methods to the `MetalPricesModuleService`. The first one is `getMetalSymbols` that returns the metal symbols as an array of strings: - -```ts title="src/modules/metal-prices/service.ts" -export default class MetalPricesModuleService { - // ... - async getMetalSymbols(): Promise { - return Object.values(MetalSymbols) - } -} -``` - -The second is `getMetalSymbol` that receives a name like `gold` and returns the corresponding metal symbol: - -```ts title="src/modules/metal-prices/service.ts" -export default class MetalPricesModuleService { - // ... - async getMetalSymbol(name: string): Promise { - const formattedName = name.charAt(0).toUpperCase() + name.slice(1).toLowerCase() - return MetalSymbols[formattedName as keyof typeof MetalSymbols] - } -} -``` - -You'll use these methods in later steps. - -### Export Module Definition - -The final piece to a module is its definition, which you export in an `index.ts` file at its root directory. This definition tells Medusa the name of the module and its service. - -So, create the file `src/modules/metal-prices/index.ts` with the following content: - -![The directory structure of the Metal Prices Module after adding the definition file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738248049/Medusa%20Resources/custom-item-price-3_imtbuw.jpg) - -```ts title="src/modules/metal-prices/index.ts" -import { Module } from "@medusajs/framework/utils" -import MetalPricesModuleService from "./service" - -export const METAL_PRICES_MODULE = "metal-prices" - -export default Module(METAL_PRICES_MODULE, { - service: MetalPricesModuleService, -}) -``` - -You use the `Module` function from the Modules SDK to create the module's definition. It accepts two parameters: - -1. The module's name, which is `metal-prices`. -2. An object with a required property `service` indicating the module's service. - -### Add Module to Medusa's Configurations - -Once you finish building the module, add it to Medusa's configurations to start using it. - -In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/metal-prices", - options: { - accessToken: process.env.GOLD_API_TOKEN, - sandbox: process.env.GOLD_API_SANDBOX === "true", - }, - }, - ], -}) -``` - -Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. - -The object also has an `options` property that accepts the module's options. You set the `accessToken` and `sandbox` options based on environment variables. - -You'll find the access token at the top of your GoldAPI.io dashboard. - -![The access token is below the "API Token" header of your GoldAPI.io dashboard.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738248335/Medusa%20Resources/Screenshot_2025-01-30_at_4.44.07_PM_xht3j4.png) - -Set the access token as an environment variable in `.env`: - -```bash -GOLD_API_TOKEN= -``` - -You'll start using the module in the next steps. - -*** - -## Step 3: Add Custom Item to Cart Workflow - -In this section, you'll implement the logic to retrieve the real-time price of a variant based on the metals in it, then add the variant to the cart with the custom price. You'll implement this logic in a workflow. - -A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in an endpoint. - -Learn more about workflows in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md) - -The workflow you'll implement in this section has the following steps: - -- [useQueryGraphStep (Retrieve Cart)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's ID and currency using Query. -- [useQueryGraphStep (Retrieve Variant)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the variant's details using Query -- [getVariantMetalPricesStep](#getvariantmetalpricesstep): Retrieve the variant's price using the third-party service. -- [addToCartWorkflow](https://docs.medusajs.com/references/medusa-workflows/addToCartWorkflow/index.html.md): Add the item with the custom price to the cart. -- [useQueryGraphStep (Retrieve Cart)](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the updated cart's details using Query. - -`useQueryGraphStep` and `addToCartWorkflow` are available through Medusa's core workflows package. You'll only implement the `getVariantMetalPricesStep`. - -### getVariantMetalPricesStep - -The `getVariantMetalPricesStep` will retrieve the real-time metal price of a variant received as an input. - -To create the step, create the file `src/workflows/steps/get-variant-metal-prices.ts` with the following content: - -![The directory structure after adding the step file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738249036/Medusa%20Resources/custom-item-price-4_kumzdc.jpg) - -```ts title="src/workflows/steps/get-variant-metal-prices.ts" -import { createStep } from "@medusajs/framework/workflows-sdk" -import { ProductVariantDTO } from "@medusajs/framework/types" -import { METAL_PRICES_MODULE } from "../../modules/metal-prices" -import MetalPricesModuleService from "../../modules/metal-prices/service" - -export type GetVariantMetalPricesStepInput = { - variant: ProductVariantDTO & { - calculated_price?: { - calculated_amount: number - } - } - currencyCode: string - quantity?: number -} - -export const getVariantMetalPricesStep = createStep( - "get-variant-metal-prices", - async ({ - variant, - currencyCode, - quantity = 1, - }: GetVariantMetalPricesStepInput, { container }) => { - const metalPricesModuleService: MetalPricesModuleService = - container.resolve(METAL_PRICES_MODULE) - - // TODO - } -) -``` - -You create a step with `createStep` from the Workflows SDK. It accepts two parameters: - -1. The step's unique name, which is `get-variant-metal-prices`. -2. An async function that receives two parameters: - - An input object with the variant, currency code, and quantity. The variant has a `calculated_price` property that holds the variant's fixed price in the Medusa application. This is useful when you want to add a fixed price to the real-time custom price, such as handling fees. - - The [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. - -In the step function, so far you only resolve the Metal Prices Module's service from the Medusa container. - -Next, you'll validate that the specified variant can have its price calculated. Add the following import at the top of the file: - -```ts title="src/workflows/steps/get-variant-metal-prices.ts" -import { MedusaError } from "@medusajs/framework/utils" -``` - -And replace the `TODO` in the step function with the following: - -```ts title="src/workflows/steps/get-variant-metal-prices.ts" -const variantMetal = variant.options.find( - (option) => option.option?.title === "Metal" -)?.value -const metalSymbol = await metalPricesModuleService - .getMetalSymbol(variantMetal || "") - -if (!metalSymbol) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Variant doesn't have metal. Make sure the variant's SKU matches a metal symbol." - ) -} - -if (!variant.weight) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Variant doesn't have weight. Make sure the variant has weight to calculate its price." - ) -} - -// TODO retrieve custom price -``` - -In the code above, you first retrieve the metal option's value from the variant's options, assuming that a variant has metals if it has a `Metal` option. Then, you retrieve the metal symbol of the option's value using the `getMetalSymbol` method of the Metal Prices Module's service. - -If the variant doesn't have a metal in its options, the option's value is not valid, or the variant doesn't have a weight, you throw an error. The weight is necessary to calculate the price based on the metal's price per weight. - -Next, you'll retrieve the real-time price of the metal using the third-party service. Replace the `TODO` with the following: - -```ts title="src/workflows/steps/get-variant-metal-prices.ts" -let price = variant.calculated_price?.calculated_amount || 0 -const weight = variant.weight -const { price: metalPrice } = await metalPricesModuleService.getMetalPrice( - metalSymbol as MetalSymbols, currencyCode -) -price += (metalPrice * weight * quantity) - -return new StepResponse(price) -``` - -In the code above, you first set the price to the variant's fixed price, if it has one. Then, you retrieve the metal's price using the `getMetalPrice` method of the Metal Prices Module's service. - -Finally, you calculate the price by multiplying the metal's price by the variant's weight and the quantity to add to the cart, then add the fixed price to it. - -Every step must return a `StepResponse` instance. The `StepResponse` constructor accepts the step's output as a parameter, which in this case is the variant's price. - -### Create addCustomToCartWorkflow - -Now that you have the `getVariantMetalPricesStep`, you can create the workflow that adds the item with custom pricing to the cart. - -Create the file `src/workflows/add-custom-to-cart.ts` with the following content: - -![The directory structure after adding the workflow file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738251380/Medusa%20Resources/custom-item-price-5_zorahv.jpg) - -```ts title="src/workflows/add-custom-to-cart.ts" highlights={workflowHighlights} -import { createWorkflow } from "@medusajs/framework/workflows-sdk" -import { useQueryGraphStep } from "@medusajs/medusa/core-flows" -import { QueryContext } from "@medusajs/framework/utils" - -type AddCustomToCartWorkflowInput = { - cart_id: string - item: { - variant_id: string - quantity: number - metadata?: Record - } -} - -export const addCustomToCartWorkflow = createWorkflow( - "add-custom-to-cart", - ({ cart_id, item }: AddCustomToCartWorkflowInput) => { - // @ts-ignore - const { data: carts } = useQueryGraphStep({ - entity: "cart", - filters: { id: cart_id }, - fields: ["id", "currency_code"], - }) - - const { data: variants } = useQueryGraphStep({ - entity: "variant", - fields: [ - "*", - "options.*", - "options.option.*", - "calculated_price.*", - ], - filters: { - id: item.variant_id, - }, - options: { - throwIfKeyNotFound: true, - }, - context: { - calculated_price: QueryContext({ - currency_code: carts[0].currency_code, - }), - }, - }).config({ name: "retrieve-variant" }) - - // TODO add more steps - } -) -``` - -You create a workflow with `createWorkflow` from the Workflows SDK. It accepts two parameters: - -1. The workflow's unique name, which is `add-custom-to-cart`. -2. A function that receives an input object with the cart's ID and the item to add to the cart. The item has the variant's ID, quantity, and optional metadata. - -In the function, you first retrieve the cart's details using the `useQueryGraphStep` helper step. This step uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md) which is a Modules SDK tool that retrieves data across modules. You use it to retrieve the cart's ID and currency code. - -You also retrieve the variant's details using the `useQueryGraphStep` helper step. You pass the variant's ID to the step's filters and specify the fields to retrieve. To retrieve the variant's price based on the cart's context, you pass the cart's currency code to the `calculated_price` context. - -Next, you'll retrieve the variant's real-time price using the `getVariantMetalPricesStep` you created earlier. First, add the following import: - -```ts title="src/workflows/add-custom-to-cart.ts" -import { - getVariantMetalPricesStep, - GetVariantMetalPricesStepInput, -} from "./steps/get-variant-metal-prices" -``` - -Then, replace the `TODO` in the workflow with the following: - -```ts title="src/workflows/add-custom-to-cart.ts" -const price = getVariantMetalPricesStep({ - variant: variants[0], - currencyCode: carts[0].currency_code, - quantity: item.quantity, -} as unknown as GetVariantMetalPricesStepInput) - -// TODO add item with custom price to cart -``` - -You execute the `getVariantMetalPricesStep` passing it the variant's details, the cart's currency code, and the quantity of the item to add to the cart. The step returns the variant's custom price. - -Next, you'll add the item with the custom price to the cart. First, add the following imports at the top of the file: - -```ts title="src/workflows/add-custom-to-cart.ts" -import { transform } from "@medusajs/framework/workflows-sdk" -import { addToCartWorkflow } from "@medusajs/medusa/core-flows" -``` - -Then, replace the `TODO` in the workflow with the following: - -```ts title="src/workflows/add-custom-to-cart.ts" -const itemToAdd = transform({ - item, - price, -}, (data) => { - return [{ - ...data.item, - unit_price: data.price, - }] -}) - -addToCartWorkflow.runAsStep({ - input: { - items: itemToAdd, - cart_id, - }, -}) - -// TODO retrieve and return cart -``` - -You prepare the item to add to the cart using `transform` from the Workflows SDK. It allows you to manipulate and create variables in a workflow. After that, you use Medusa's `addToCartWorkflow` to add the item with the custom price to the cart. - -A workflow's constructor function has some constraints in implementation, which is why you need to use `transform` for variable manipulation. Learn more about these constraints in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md). - -Lastly, you'll retrieve the cart's details again and return them. Add the following import at the beginning of the file: - -```ts title="src/workflows/add-custom-to-cart.ts" -import { WorkflowResponse } from "@medusajs/framework/workflows-sdk" -``` - -And replace the last `TODO` in the workflow with the following: - -```ts title="src/workflows/add-custom-to-cart.ts" -// @ts-ignore -const { data: updatedCarts } = useQueryGraphStep({ - entity: "cart", - filters: { id: cart_id }, - fields: ["id", "items.*"], -}).config({ name: "refetch-cart" }) - -return new WorkflowResponse({ - cart: updatedCarts[0], -}) -``` - -In the code above, you retrieve the updated cart's details using the `useQueryGraphStep` helper step. To return data from the workflow, you create and return a `WorkflowResponse` instance. It accepts as a parameter the data to return, which is the updated cart. - -In the next step, you'll use the workflow in a custom route to add an item with a custom price to the cart. - -*** - -## Step 4: Create Add Custom Item to Cart API Route - -Now that you've implemented the logic to add an item with a custom price to the cart, you'll expose this functionality in an API route. - -An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. You'll create an API route at the path `/store/carts/:id/line-items-metals` that executes the workflow from the previous step to add a product variant with custom price to the cart. - -Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). - -### Create API Route - -An API route is created in a `route.ts` file under a sub-directory of the `src/api` directory. - -The path of the API route is the file's path relative to `src/api`. So, to create the `/store/carts/:id/line-items-metals` API route, create the file `src/api/store/carts/[id]/line-items-metals/route.ts` with the following content: - -![The directory structure after adding the API route file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738252712/Medusa%20Resources/custom-item-price-6_deecbu.jpg) - -```ts title="src/api/store/carts/[id]/line-items-metals/route.ts" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework" -import { HttpTypes } from "@medusajs/framework/types" -import { addCustomToCartWorkflow } from "../../../../../workflows/add-custom-to-cart" - -export const POST = async ( - req: MedusaRequest, - res: MedusaResponse -) => { - const { id } = req.params - const item = req.validatedBody - - const { result } = await addCustomToCartWorkflow(req.scope) - .run({ - input: { - cart_id: id, - item, - }, - }) - - res.status(200).json({ cart: result.cart }) -} -``` - -Since you export a `POST` function in this file, you're exposing a `POST` API route at `/store/carts/:id/line-items-metals`. The route handler function accepts two parameters: - -1. A request object with details and context on the request, such as path and body parameters. -2. A response object to manipulate and send the response. - -In the function, you retrieve the cart's ID from the path parameter, and the item's details from the request body. This API route will accept the same request body parameters as Medusa's [Add Item to Cart API Route](https://docs.medusajs.com/api/store#carts_postcartsidlineitems). - -Then, you execute the `addCustomToCartWorkflow` by invoking it, passing it the Medusa container, which is available in the request's `scope` property, then executing its `run` method. You pass the workflow's input object with the cart's ID and the item to add to the cart. - -Finally, you return a response with the updated cart's details. - -### Add Request Body Validation Middleware - -To ensure that the request body contains the required parameters, you'll add a middleware that validates the incoming request's body based on a defined schema. - -A middleware is a function executed before the API route when a request is sent to it. You define middlewares in Medusa in the `src/api/middlewares.ts` directory. - -Learn more about middlewares in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md). - -To add a validation middleware to the custom API route, create the file `src/api/middlewares.ts` with the following content: - -![The directory structure after adding the middleware file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253099/Medusa%20Resources/custom-item-price-7_l7iw2a.jpg) - -```ts title="src/api/middlewares.ts" -import { - defineMiddlewares, - validateAndTransformBody, -} from "@medusajs/framework/http" -import { - StoreAddCartLineItem, -} from "@medusajs/medusa/api/store/carts/validators" - -export default defineMiddlewares({ - routes: [ - { - matcher: "/store/carts/:id/line-items-metals", - method: "POST", - middlewares: [ - validateAndTransformBody( - StoreAddCartLineItem - ), - ], - }, - ], -}) -``` - -In this file, you export the middlewares definition using `defineMiddlewares` from the Medusa Framework. This function accepts an object having a `routes` property, which is an array of middleware configurations to apply on routes. - -You pass in the `routes` array an object having the following properties: - -- `matcher`: The route to apply the middleware on. -- `method`: The HTTP method to apply the middleware on for the specified API route. -- `middlewares`: An array of the middlewares to apply. You apply the `validateAndTransformBody` middleware, which validates the request body based on the `StoreAddCartLineItem` schema. This validation schema is the same schema used for Medusa's [Add Item to Cart API Route](https://docs.medusajs.com/api/store#carts_postcartsidlineitems). - -Any request sent to the `/store/carts/:id/line-items-metals` API route will now fail if it doesn't have the required parameters. - -Learn more about API route validation in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/validation/index.html.md). - -### Prepare to Test API Route - -Before you test the API route, you'll prepare and retrieve the necessary data to add a product variant with a custom price to the cart. - -#### Create Product with Metal Variant - -You'll first create a product that has a `Metal` option, and variant(s) with values for this option. - -Start the Medusa application with the following command: - -```bash npm2yarn -npm run dev -``` - -Then, open the Medusa Admin dashboard at `localhost:9000/app` and log in with the email and password you created when you installed the Medusa application in the first step. - -Once you log in, click on Products in the sidebar, then click the Create button at the top right. - -![Click on Products in the sidebar at the left, then click on the Create button at the top right of the content](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253415/Medusa%20Resources/Screenshot_2025-01-30_at_6.09.36_PM_ee0jr2.png) - -Then, in the Create Product form: - -1. Enter a name for the product, and optionally enter other details like description. -2. Enable the "Yes, this is a product with variants" toggle. -3. Under Product Options, enter "Metal" for the title, and enter "Gold" for the values. - -Once you're done, click the Continue button. - -![Fill in the product details, enable the "Yes, this is a product with variants" toggle, and add the "Metal" option with "Gold" value](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253520/Medusa%20Resources/Screenshot_2025-01-30_at_6.11.29_PM_lqxth9.png) - -You can skip the next two steps by clicking the Continue button again, then the Publish button. - -Once you're done, the product's page will open. You'll now add weight to the product's Gold variant.

To do that: - -1. Click on the three-dots icon at the top right of the Variants section. -2. Choose "Edit Prices" from the dropdown. - -![Click on the three-dots icon at the top right of the Variants section, then choose "Edit Prices"](https://res.cloudinary.com/dza7lstvk/image/upload/v1738255203/Medusa%20Resources/Screenshot_2025-01-30_at_6.39.35_PM_s3jpxh.png) - -For each cell in the table, either enter a fixed price for the specified currency or leave it as `0`. Once you're done, click the Save button. - -![Enter fixed prices for the variant in the table, then click the Save button](https://res.cloudinary.com/dza7lstvk/image/upload/v1738255272/Medusa%20Resources/Screenshot_2025-01-30_at_6.40.45_PM_zw1l59.png) - -You'll use this variant to add it to the cart later. You can find its ID by clicking on the variant, opening its details page. Then, on the details page, click on the icon at the right of the JSON section, and copy the ID from the JSON data. - -![Click on the icon at the right of the JSON section to copy the variant's ID](https://res.cloudinary.com/dza7lstvk/image/upload/v1738254314/Medusa%20Resources/Screenshot_2025-01-30_at_6.24.49_PM_ka7xew.png) - -#### Retrieve Publishable API Key - -All requests sent to API routes starting with `/store` must have a publishable API key in the header. This ensures the request's operations are scoped to the publishable API key's associated sales channels. For example, products that aren't available in a cart's sales channel can't be added to it. - -To retrieve the publishable API key, on the Medusa Admin: - -1. Click on Settings in the sidebar at the bottom left. -2. Click on Publishable API Keys from the sidebar, then click on a publishable API key in the list. - -![Click on publishable API keys in the Settings sidebar, then click on a publishable API key in the list](https://res.cloudinary.com/dza7lstvk/image/upload/v1738254523/Medusa%20Resources/Screenshot_2025-01-30_at_6.28.17_PM_mldscc.png) - -3. Click on the publishable API key to copy it. - -![Click on the publishable API key to copy it](https://res.cloudinary.com/dza7lstvk/image/upload/v1738254601/Medusa%20Resources/Screenshot_2025-01-30_at_6.29.26_PM_vvatki.png) - -You'll use this key when you test the API route. - -### Test API Route - -To test out the API route, you need to create a cart. A cart must be associated with a region. So, to retrieve the ID of a region in your store, send a `GET` request to the `/store/regions` API route: - -```bash -curl 'localhost:9000/store/regions' \ --H 'x-publishable-api-key: {api_key}' -``` - -Make sure to replace `{api_key}` with the publishable API key you copied earlier. - -This will return a list of regions. Copy the ID of one of the regions. - -Then, send a `POST` request to the `/store/carts` API route to create a cart: - -```bash -curl -X POST 'localhost:9000/store/carts' \ --H 'x-publishable-api-key: {api_key}' \ --H 'Content-Type: application/json' \ ---data '{ - "region_id": "{region_id}" -}' -``` - -Make sure to replace `{api_key}` with the publishable API key you copied earlier, and `{region_id}` with the ID of a region from the previous request. - -This will return the created cart. Copy the ID of the cart to use it next. - -Finally, to add the Gold variant to the cart with a custom price, send a `POST` request to the `/store/carts/:id/line-items-metals` API route: - -```bash -curl -X POST 'localhost:9000/store/carts/{cart_id}/line-items-metals' \ --H 'x-publishable-api-key: {api_key}' \ --H 'Content-Type: application/json' \ ---data '{ - "variant_id": "{variant_id}", - "quantity": 1 -}' -``` - -Make sure to replace: - -- `{api_key}` with the publishable API key you copied earlier. -- `{cart_id}` with the ID of the cart you created. -- `{variant_id}` with the ID of the Gold variant you created. - -This will return the cart's details, where you can see in its `items` array the item with the custom price: - -```json title="Example Response" -{ - "cart": { - "items": [ - { - "variant_id": "{variant_id}", - "quantity": 1, - "is_custom_price": true, - // example custom price - "unit_price": 2000 - } - ] - } -} -``` - -The price will be the result of the calculation you've implemented earlier, which is the fixed price of the variant plus the real-time price of the metal, multiplied by the weight of the variant and the quantity added to the cart. - -This price will be reflected in the cart's total price, and you can proceed to checkout with the custom-priced item. - -*** - -## Next Steps - -You've now implemented custom item pricing in Medusa. You can also customize the [storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) to use the new API route to add custom-priced items to the cart. - -If you're new to Medusa, check out the [main documentation](https://docs.medusajs.com/docs/learn/index.html.md), where you'll get a more in-depth learning of all the concepts you've used in this guide and more. - -To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). - - # Implement Quote Management in Medusa In this guide, you'll learn how to implement quote management in Medusa. @@ -39971,6 +39287,795 @@ If you're new to Medusa, check out the [main documentation](https://docs.medusaj To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). +# Implement Custom Line Item Pricing in Medusa + +In this guide, you'll learn how to add line items with custom prices to a cart in Medusa. + +When you install a Medusa application, you get a fully-fledged commerce platform with a Framework for customization. The Medusa application's commerce features are built around [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md) which are available out-of-the-box. These features include managing carts and adding line items to them. + +By default, you can add product variants to the cart, where the price of its associated line item is based on the product variant's price. However, you can build customizations to add line items with custom prices to the cart. This is useful when integrating an Enterprise Resource Planning (ERP), Product Information Management (PIM), or other third-party services that provide real-time prices for your products. + +To showcase how to add line items with custom prices to the cart, this guide uses [GoldAPI.io](https://www.goldapi.io) as an example of a third-party system that you can integrate for real-time prices.

You'll use this module later to retrieve the real-time price of a product variant based on the metals in it, and add it to the cart with that custom price. + +Learn more about modules in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md). + +### Create Module Directory + +A module is created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/metal-prices`. + +![Diagram showcasing the module directory to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1738247192/Medusa%20Resources/custom-item-price-1_q16evr.jpg) + +### Create Module's Service + +You define a module's functionalities in a service. A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, which is useful if your module defines tables in the database, or connect to a third-party service. + +In this section, you'll create the Metal Prices Module's service that connects to the GoldAPI.io service to retrieve real-time prices for metals. + +Start by creating the file `src/modules/metal-prices/service.ts` with the following content: + +![Diagram showcasing the service file to create](https://res.cloudinary.com/dza7lstvk/image/upload/v1738247303/Medusa%20Resources/custom-item-price-2_eaefis.jpg) + +```ts title="src/modules/metal-prices/service.ts" +type Options = { + accessToken: string + sandbox?: boolean +} + +export default class MetalPricesModuleService { + protected options_: Options + + constructor({}, options: Options) { + this.options_ = options + } +} +``` + +A module can accept options that are passed to its service. You define an `Options` type that indicates the options the module accepts. It accepts two options: + +- `accessToken`: The access token for the GoldAPI.io service. +- `sandbox`: A boolean that indicates whether to simulate sending requests to the GoldAPI.io service. This is useful when running in a test environment. + +The service's constructor receives the module's options as a second parameter. You store the options in the service's `options_` property. + +A module has a container of Medusa Framework tools and local resources in the module that you can access in the service constructor's first parameter. Learn more in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/container/index.html.md). + +#### Add Method to Retrieve Metal Prices + +Next, you'll add the method to retrieve the metal prices from the third-party service. + +First, add the following types at the beginning of `src/modules/metal-prices/service.ts`: + +```ts title="src/modules/metal-prices/service.ts" +export enum MetalSymbols { + Gold = "XAU", + Silver = "XAG", + Platinum = "XPT", + Palladium = "XPD" +} + +export type PriceResponse = { + metal: MetalSymbols + currency: string + exchange: string + symbol: string + price: number + [key: string]: unknown +} + +``` + +The `MetalSymbols` enum defines the symbols for metals like Gold, Silver, Platinum, and Palladium. The `PriceResponse` type defines the structure of the response from the GoldAPI.io's endpoint. + +Next, add the method `getMetalPrices` to the `MetalPricesModuleService` class: + +```ts title="src/modules/metal-prices/service.ts" +import { MedusaError } from "@medusajs/framework/utils" + +// ... + +export default class MetalPricesModuleService { + // ... + async getMetalPrice( + symbol: MetalSymbols, + currency: string + ): Promise { + const upperCaseSymbol = symbol.toUpperCase() + const upperCaseCurrency = currency.toUpperCase() + + return fetch(`https://www.goldapi.io/api/${upperCaseSymbol}/${upperCaseCurrency}`, { + headers: { + "x-access-token": this.options_.accessToken, + "Content-Type": "application/json", + }, + redirect: "follow", + }).then((response) => response.json()) + .then((response) => { + if (response.error) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + response.error + ) + } + + return response + }) + } +} +``` + +The `getMetalPrice` method accepts the metal symbol and currency as parameters. You send a request to GoldAPI.io's `/api/{symbol}/{currency}` endpoint to retrieve the metal's price, also passing the access token in the request's headers. + +If the response contains an error, you throw a `MedusaError` with the error message. Otherwise, you return the response, which is of type `PriceResponse`. + +#### Add Helper Methods + +You'll also add two helper methods to the `MetalPricesModuleService`. The first one is `getMetalSymbols` that returns the metal symbols as an array of strings: + +```ts title="src/modules/metal-prices/service.ts" +export default class MetalPricesModuleService { + // ... + async getMetalSymbols(): Promise { + return Object.values(MetalSymbols) + } +} +``` + +The second is `getMetalSymbol` that receives a name like `gold` and returns the corresponding metal symbol: + +```ts title="src/modules/metal-prices/service.ts" +export default class MetalPricesModuleService { + // ... + async getMetalSymbol(name: string): Promise { + const formattedName = name.charAt(0).toUpperCase() + name.slice(1).toLowerCase() + return MetalSymbols[formattedName as keyof typeof MetalSymbols] + } +} +``` + +You'll use these methods in later steps. + +### Export Module Definition + +The final piece to a module is its definition, which you export in an `index.ts` file at its root directory. This definition tells Medusa the name of the module and its service. + +So, create the file `src/modules/metal-prices/index.ts` with the following content: + +![The directory structure of the Metal Prices Module after adding the definition file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738248049/Medusa%20Resources/custom-item-price-3_imtbuw.jpg) + +```ts title="src/modules/metal-prices/index.ts" +import { Module } from "@medusajs/framework/utils" +import MetalPricesModuleService from "./service" + +export const METAL_PRICES_MODULE = "metal-prices" + +export default Module(METAL_PRICES_MODULE, { + service: MetalPricesModuleService, +}) +``` + +You use the `Module` function from the Modules SDK to create the module's definition. It accepts two parameters: + +1. The module's name, which is `metal-prices`. +2. An object with a required property `service` indicating the module's service. + +### Add Module to Medusa's Configurations + +Once you finish building the module, add it to Medusa's configurations to start using it. + +In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/metal-prices", + options: { + accessToken: process.env.GOLD_API_TOKEN, + sandbox: process.env.GOLD_API_SANDBOX === "true", + }, + }, + ], +}) +``` + +Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. + +The object also has an `options` property that accepts the module's options. You set the `accessToken` and `sandbox` options based on environment variables. + +You'll find the access token at the top of your GoldAPI.io dashboard. + +![The access token is below the "API Token" header of your GoldAPI.io dashboard.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738248335/Medusa%20Resources/Screenshot_2025-01-30_at_4.44.07_PM_xht3j4.png) + +Set the access token as an environment variable in `.env`: + +```bash +GOLD_API_TOKEN= +``` + +You'll start using the module in the next steps. + +*** + +## Step 3: Add Custom Item to Cart Workflow + +In this section, you'll implement the logic to retrieve the real-time price of a variant based on the metals in it, then add the variant to the cart with the custom price. You'll implement this logic in a workflow. + +A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features.

You'll only implement the `getVariantMetalPricesStep`. + +### getVariantMetalPricesStep + +The `getVariantMetalPricesStep` will retrieve the real-time metal price of a variant received as an input. + +To create the step, create the file `src/workflows/steps/get-variant-metal-prices.ts` with the following content: + +![The directory structure after adding the step file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738249036/Medusa%20Resources/custom-item-price-4_kumzdc.jpg) + +```ts title="src/workflows/steps/get-variant-metal-prices.ts" +import { createStep } from "@medusajs/framework/workflows-sdk" +import { ProductVariantDTO } from "@medusajs/framework/types" +import { METAL_PRICES_MODULE } from "../../modules/metal-prices" +import MetalPricesModuleService from "../../modules/metal-prices/service" + +export type GetVariantMetalPricesStepInput = { + variant: ProductVariantDTO & { + calculated_price?: { + calculated_amount: number + } + } + currencyCode: string + quantity?: number +} + +export const getVariantMetalPricesStep = createStep( + "get-variant-metal-prices", + async ({ + variant, + currencyCode, + quantity = 1, + }: GetVariantMetalPricesStepInput, { container }) => { + const metalPricesModuleService: MetalPricesModuleService = + container.resolve(METAL_PRICES_MODULE) + + // TODO + } +) +``` + +You create a step with `createStep` from the Workflows SDK. It accepts two parameters: + +1. The step's unique name, which is `get-variant-metal-prices`. +2. An async function that receives two parameters: + - An input object with the variant, currency code, and quantity. The variant has a `calculated_price` property that holds the variant's fixed price in the Medusa application. This is useful when you want to add a fixed price to the real-time custom price, such as handling fees. + - The [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. + +In the step function, so far you only resolve the Metal Prices Module's service from the Medusa container. + +Next, you'll validate that the specified variant can have its price calculated. Add the following import at the top of the file: + +```ts title="src/workflows/steps/get-variant-metal-prices.ts" +import { MedusaError } from "@medusajs/framework/utils" +``` + +And replace the `TODO` in the step function with the following: + +```ts title="src/workflows/steps/get-variant-metal-prices.ts" +const variantMetal = variant.options.find( + (option) => option.option?.title === "Metal" +)?.value +const metalSymbol = await metalPricesModuleService + .getMetalSymbol(variantMetal || "") + +if (!metalSymbol) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Variant doesn't have metal. Make sure the variant's SKU matches a metal symbol." + ) +} + +if (!variant.weight) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Variant doesn't have weight. Make sure the variant has weight to calculate its price." + ) +} + +// TODO retrieve custom price +``` + +In the code above, you first retrieve the metal option's value from the variant's options, assuming that a variant has metals if it has a `Metal` option. Then, you retrieve the metal symbol of the option's value using the `getMetalSymbol` method of the Metal Prices Module's service. + +If the variant doesn't have a metal in its options, the option's value is not valid, or the variant doesn't have a weight, you throw an error. The weight is necessary to calculate the price based on the metal's price per weight. + +Next, you'll retrieve the real-time price of the metal using the third-party service. Replace the `TODO` with the following: + +```ts title="src/workflows/steps/get-variant-metal-prices.ts" +let price = variant.calculated_price?.calculated_amount || 0 +const weight = variant.weight +const { price: metalPrice } = await metalPricesModuleService.getMetalPrice( + metalSymbol as MetalSymbols, currencyCode +) +price += (metalPrice * weight * quantity) + +return new StepResponse(price) +``` + +In the code above, you first set the price to the variant's fixed price, if it has one. Then, you retrieve the metal's price using the `getMetalPrice` method of the Metal Prices Module's service. + +Finally, you calculate the price by multiplying the metal's price by the variant's weight and the quantity to add to the cart, then add the fixed price to it. + +Every step must return a `StepResponse` instance. The `StepResponse` constructor accepts the step's output as a parameter, which in this case is the variant's price. + +### Create addCustomToCartWorkflow + +Now that you have the `getVariantMetalPricesStep`, you can create the workflow that adds the item with custom pricing to the cart. + +Create the file `src/workflows/add-custom-to-cart.ts` with the following content: + +![The directory structure after adding the workflow file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738251380/Medusa%20Resources/custom-item-price-5_zorahv.jpg) + +```ts title="src/workflows/add-custom-to-cart.ts" highlights={workflowHighlights} +import { createWorkflow } from "@medusajs/framework/workflows-sdk" +import { useQueryGraphStep } from "@medusajs/medusa/core-flows" +import { QueryContext } from "@medusajs/framework/utils" + +type AddCustomToCartWorkflowInput = { + cart_id: string + item: { + variant_id: string + quantity: number + metadata?: Record + } +} + +export const addCustomToCartWorkflow = createWorkflow( + "add-custom-to-cart", + ({ cart_id, item }: AddCustomToCartWorkflowInput) => { + // @ts-ignore + const { data: carts } = useQueryGraphStep({ + entity: "cart", + filters: { id: cart_id }, + fields: ["id", "currency_code"], + }) + + const { data: variants } = useQueryGraphStep({ + entity: "variant", + fields: [ + "*", + "options.*", + "options.option.*", + "calculated_price.*", + ], + filters: { + id: item.variant_id, + }, + options: { + throwIfKeyNotFound: true, + }, + context: { + calculated_price: QueryContext({ + currency_code: carts[0].currency_code, + }), + }, + }).config({ name: "retrieve-variant" }) + + // TODO add more steps + } +) +``` + +You create a workflow with `createWorkflow` from the Workflows SDK. It accepts two parameters: + +1. The workflow's unique name, which is `add-custom-to-cart`. +2. A function that receives an input object with the cart's ID and the item to add to the cart. The item has the variant's ID, quantity, and optional metadata. + +In the function, you first retrieve the cart's details using the `useQueryGraphStep` helper step. This step uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md) which is a Modules SDK tool that retrieves data across modules. You use it to retrieve the cart's ID and currency code. + +You also retrieve the variant's details using the `useQueryGraphStep` helper step. You pass the variant's ID to the step's filters and specify the fields to retrieve. To retrieve the variant's price based on the cart's context, you pass the cart's currency code to the `calculated_price` context. + +Next, you'll retrieve the variant's real-time price using the `getVariantMetalPricesStep` you created earlier. First, add the following import: + +```ts title="src/workflows/add-custom-to-cart.ts" +import { + getVariantMetalPricesStep, + GetVariantMetalPricesStepInput, +} from "./steps/get-variant-metal-prices" +``` + +Then, replace the `TODO` in the workflow with the following: + +```ts title="src/workflows/add-custom-to-cart.ts" +const price = getVariantMetalPricesStep({ + variant: variants[0], + currencyCode: carts[0].currency_code, + quantity: item.quantity, +} as unknown as GetVariantMetalPricesStepInput) + +// TODO add item with custom price to cart +``` + +You execute the `getVariantMetalPricesStep` passing it the variant's details, the cart's currency code, and the quantity of the item to add to the cart. The step returns the variant's custom price. + +Next, you'll add the item with the custom price to the cart. First, add the following imports at the top of the file: + +```ts title="src/workflows/add-custom-to-cart.ts" +import { transform } from "@medusajs/framework/workflows-sdk" +import { addToCartWorkflow } from "@medusajs/medusa/core-flows" +``` + +Then, replace the `TODO` in the workflow with the following: + +```ts title="src/workflows/add-custom-to-cart.ts" +const itemToAdd = transform({ + item, + price, +}, (data) => { + return [{ + ...data.item, + unit_price: data.price, + }] +}) + +addToCartWorkflow.runAsStep({ + input: { + items: itemToAdd, + cart_id, + }, +}) + +// TODO retrieve and return cart +``` + +You prepare the item to add to the cart using `transform` from the Workflows SDK. It allows you to manipulate and create variables in a workflow. After that, you use Medusa's `addToCartWorkflow` to add the item with the custom price to the cart. + +A workflow's constructor function has some constraints in implementation, which is why you need to use `transform` for variable manipulation. Learn more about these constraints in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md). + +Lastly, you'll retrieve the cart's details again and return them. Add the following import at the beginning of the file: + +```ts title="src/workflows/add-custom-to-cart.ts" +import { WorkflowResponse } from "@medusajs/framework/workflows-sdk" +``` + +And replace the last `TODO` in the workflow with the following: + +```ts title="src/workflows/add-custom-to-cart.ts" +// @ts-ignore +const { data: updatedCarts } = useQueryGraphStep({ + entity: "cart", + filters: { id: cart_id }, + fields: ["id", "items.*"], +}).config({ name: "refetch-cart" }) + +return new WorkflowResponse({ + cart: updatedCarts[0], +}) +``` + +In the code above, you retrieve the updated cart's details using the `useQueryGraphStep` helper step. To return data from the workflow, you create and return a `WorkflowResponse` instance. It accepts as a parameter the data to return, which is the updated cart. + +In the next step, you'll use the workflow in a custom route to add an item with a custom price to the cart. + +*** + +## Step 4: Create Add Custom Item to Cart API Route + +Now that you've implemented the logic to add an item with a custom price to the cart, you'll expose this functionality in an API route. + +An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. You'll create an API route at the path `/store/carts/:id/line-items-metals` that executes the workflow from the previous step to add a product variant with custom price to the cart. + +Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). + +### Create API Route + +An API route is created in a `route.ts` file under a sub-directory of the `src/api` directory. + +The path of the API route is the file's path relative to `src/api`. So, to create the `/store/carts/:id/line-items-metals` API route, create the file `src/api/store/carts/[id]/line-items-metals/route.ts` with the following content: + +![The directory structure after adding the API route file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738252712/Medusa%20Resources/custom-item-price-6_deecbu.jpg) + +```ts title="src/api/store/carts/[id]/line-items-metals/route.ts" +import { MedusaRequest, MedusaResponse } from "@medusajs/framework" +import { HttpTypes } from "@medusajs/framework/types" +import { addCustomToCartWorkflow } from "../../../../../workflows/add-custom-to-cart" + +export const POST = async ( + req: MedusaRequest, + res: MedusaResponse +) => { + const { id } = req.params + const item = req.validatedBody + + const { result } = await addCustomToCartWorkflow(req.scope) + .run({ + input: { + cart_id: id, + item, + }, + }) + + res.status(200).json({ cart: result.cart }) +} +``` + +Since you export a `POST` function in this file, you're exposing a `POST` API route at `/store/carts/:id/line-items-metals`. The route handler function accepts two parameters: + +1. A request object with details and context on the request, such as path and body parameters. +2. A response object to manipulate and send the response. + +In the function, you retrieve the cart's ID from the path parameter, and the item's details from the request body. This API route will accept the same request body parameters as Medusa's [Add Item to Cart API Route](https://docs.medusajs.com/api/store#carts_postcartsidlineitems). + +Then, you execute the `addCustomToCartWorkflow` by invoking it, passing it the Medusa container, which is available in the request's `scope` property, then executing its `run` method. You pass the workflow's input object with the cart's ID and the item to add to the cart. + +Finally, you return a response with the updated cart's details. + +### Add Request Body Validation Middleware + +To ensure that the request body contains the required parameters, you'll add a middleware that validates the incoming request's body based on a defined schema. + +A middleware is a function executed before the API route when a request is sent to it. You define middlewares in Medusa in the `src/api/middlewares.ts` directory. + +Learn more about middlewares in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/middlewares/index.html.md). + +To add a validation middleware to the custom API route, create the file `src/api/middlewares.ts` with the following content: + +![The directory structure after adding the middleware file.](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253099/Medusa%20Resources/custom-item-price-7_l7iw2a.jpg) + +```ts title="src/api/middlewares.ts" +import { + defineMiddlewares, + validateAndTransformBody, +} from "@medusajs/framework/http" +import { + StoreAddCartLineItem, +} from "@medusajs/medusa/api/store/carts/validators" + +export default defineMiddlewares({ + routes: [ + { + matcher: "/store/carts/:id/line-items-metals", + method: "POST", + middlewares: [ + validateAndTransformBody( + StoreAddCartLineItem + ), + ], + }, + ], +}) +``` + +In this file, you export the middlewares definition using `defineMiddlewares` from the Medusa Framework. This function accepts an object having a `routes` property, which is an array of middleware configurations to apply on routes. + +You pass in the `routes` array an object having the following properties: + +- `matcher`: The route to apply the middleware on. +- `method`: The HTTP method to apply the middleware on for the specified API route. +- `middlewares`: An array of the middlewares to apply. You apply the `validateAndTransformBody` middleware, which validates the request body based on the `StoreAddCartLineItem` schema. This validation schema is the same schema used for Medusa's [Add Item to Cart API Route](https://docs.medusajs.com/api/store#carts_postcartsidlineitems). + +Any request sent to the `/store/carts/:id/line-items-metals` API route will now fail if it doesn't have the required parameters. + +Learn more about API route validation in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/validation/index.html.md). + +### Prepare to Test API Route + +Before you test the API route, you'll prepare and retrieve the necessary data to add a product variant with a custom price to the cart. + +#### Create Product with Metal Variant + +You'll first create a product that has a `Metal` option, and variant(s) with values for this option. + +Start the Medusa application with the following command: + +```bash npm2yarn +npm run dev +``` + +Then, open the Medusa Admin dashboard at `localhost:9000/app` and log in with the email and password you created when you installed the Medusa application in the first step. + +Once you log in, click on Products in the sidebar, then click the Create button at the top right. + +![Click on Products in the sidebar at the left, then click on the Create button at the top right of the content](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253415/Medusa%20Resources/Screenshot_2025-01-30_at_6.09.36_PM_ee0jr2.png) + +Then, in the Create Product form: + +1. Enter a name for the product, and optionally enter other details like description. +2. Enable the "Yes, this is a product with variants" toggle. +3. Under Product Options, enter "Metal" for the title, and enter "Gold" for the values. + +Once you're done, click the Continue button. + +![Fill in the product details, enable the "Yes, this is a product with variants" toggle, and add the "Metal" option with "Gold" value](https://res.cloudinary.com/dza7lstvk/image/upload/v1738253520/Medusa%20Resources/Screenshot_2025-01-30_at_6.11.29_PM_lqxth9.png) + +You can skip the next two steps by clicking the Continue button again, then the Publish button. + +Once you're done, the product's page will open.

To do that: + +1. Click on the three-dots icon at the top right of the Variants section. +2. Choose "Edit Prices" from the dropdown. + +![Click on the three-dots icon at the top right of the Variants section, then choose "Edit Prices"](https://res.cloudinary.com/dza7lstvk/image/upload/v1738255203/Medusa%20Resources/Screenshot_2025-01-30_at_6.39.35_PM_s3jpxh.png) + +For each cell in the table, either enter a fixed price for the specified currency or leave it as `0`.

This ensures the request's operations are scoped to the publishable API key's associated sales channels. For example, products that aren't available in a cart's sales channel can't be added to it. + +To retrieve the publishable API key, on the Medusa Admin: + +1. Click on Settings in the sidebar at the bottom left. +2.

A cart must be associated with a region. So, to retrieve the ID of a region in your store, send a `GET` request to the `/store/regions` API route: + +```bash +curl 'localhost:9000/store/regions' \ +-H 'x-publishable-api-key: {api_key}' +``` + +Make sure to replace `{api_key}` with the publishable API key you copied earlier. + +This will return a list of regions. Copy the ID of one of the regions. + +Then, send a `POST` request to the `/store/carts` API route to create a cart: + +```bash +curl -X POST 'localhost:9000/store/carts' \ +-H 'x-publishable-api-key: {api_key}' \ +-H 'Content-Type: application/json' \ +--data '{ + "region_id": "{region_id}" +}' +``` + +Make sure to replace `{api_key}` with the publishable API key you copied earlier, and `{region_id}` with the ID of a region from the previous request. + +This will return the created cart. Copy the ID of the cart to use it next. + +Finally, to add the Gold variant to the cart with a custom price, send a `POST` request to the `/store/carts/:id/line-items-metals` API route: + +```bash +curl -X POST 'localhost:9000/store/carts/{cart_id}/line-items-metals' \ +-H 'x-publishable-api-key: {api_key}' \ +-H 'Content-Type: application/json' \ +--data '{ + "variant_id": "{variant_id}", + "quantity": 1 +}' +``` + +Make sure to replace: + +- `{api_key}` with the publishable API key you copied earlier. +- `{cart_id}` with the ID of the cart you created. +- `{variant_id}` with the ID of the Gold variant you created. + +This will return the cart's details, where you can see in its `items` array the item with the custom price: + +```json title="Example Response" +{ + "cart": { + "items": [ + { + "variant_id": "{variant_id}", + "quantity": 1, + "is_custom_price": true, + // example custom price + "unit_price": 2000 + } + ] + } +} +``` + +The price will be the result of the calculation you've implemented earlier, which is the fixed price of the variant plus the real-time price of the metal, multiplied by the weight of the variant and the quantity added to the cart. + +This price will be reflected in the cart's total price, and you can proceed to checkout with the custom-priced item. + +*** + +## Next Steps + +You've now implemented custom item pricing in Medusa.

Medusa integrates the module into your application without implications or side effects on your setup. - -In the module, you define the data models necessary for a feature and the logic to manage these data models. Later, you can build commerce flows around your module. - -In this step, you'll build a Loyalty Module that defines the necessary data models to store and manage loyalty points for customers. - -Refer to the [Modules documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md) to learn more. - -### Create Module Directory - -Modules are created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/loyalty`. - -### Create Data Models - -A data model represents a table in the database. You create data models using Medusa's Data Model Language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. - -Refer to the [Data Models documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#1-create-data-model/index.html.md) to learn more. - -For the Loyalty Module, you need to define a `LoyaltyPoint` data model that represents a customer's loyalty points. So, create the file `src/modules/loyalty/models/loyalty-point.ts` with the following content: - -```ts title="src/modules/loyalty/models/loyalty-point.ts" highlights={dmlHighlights} -import { model } from "@medusajs/framework/utils" - -const LoyaltyPoint = model.define("loyalty_point", { - id: model.id().primaryKey(), - points: model.number().default(0), - customer_id: model.text().unique("IDX_LOYALTY_CUSTOMER_ID"), -}) - -export default LoyaltyPoint -``` - -You define the `LoyaltyPoint` data model using the `model.define` method of the DML. It accepts the data model's table name as a first parameter, and the model's schema object as a second parameter. - -The `LoyaltyPoint` data model has the following properties: - -- `id`: A unique ID for the loyalty points. -- `points`: The number of loyalty points a customer has. -- `customer_id`: The ID of the customer who owns the loyalty points. This property has a unique index to ensure that each customer has only one record in the `loyalty_point` table. - -Learn more about defining data model properties in the [Property Types documentation](https://docs.medusajs.com/docs/learn/fundamentals/data-models/properties/index.html.md). - -### Create Module's Service - -You now have the necessary data model in the Loyalty Module, but you'll need to manage its records. You do this by creating a service in the module. - -A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, allowing you to manage your data models, or connect to a third-party service, which is useful if you're integrating with external services. - -Refer to the [Module Service documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#2-create-service/index.html.md) to learn more. - -To create the Loyalty Module's service, create the file `src/modules/loyalty/service.ts` with the following content: - -```ts title="src/modules/loyalty/service.ts" -import { MedusaError, MedusaService } from "@medusajs/framework/utils" -import LoyaltyPoint from "./models/loyalty-point" -import { InferTypeOf } from "@medusajs/framework/types" - -type LoyaltyPoint = InferTypeOf - -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - // TODO add methods -} - -export default LoyaltyModuleService -``` - -The `LoyaltyModuleService` extends `MedusaService` from the Modules SDK which generates a class with data-management methods for your module's data models. This saves you time on implementing Create, Read, Update, and Delete (CRUD) methods. - -So, the `LoyaltyModuleService` class now has methods like `createLoyaltyPoints` and `retrieveLoyaltyPoint`. - -Find all methods generated by the `MedusaService` in [the Service Factory reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/service-factory-reference/index.html.md). - -#### Add Methods to the Service - -Aside from the basic CRUD methods, you need to add methods that handle custom functionalities related to loyalty points. - -First, you need a method that adds loyalty points for a customer. Add the following method to the `LoyaltyModuleService`: - -```ts title="src/modules/loyalty/service.ts" -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - async addPoints(customerId: string, points: number): Promise { - const existingPoints = await this.listLoyaltyPoints({ - customer_id: customerId, - }) - - if (existingPoints.length > 0) { - return await this.updateLoyaltyPoints({ - id: existingPoints[0].id, - points: existingPoints[0].points + points, - }) - } - - return await this.createLoyaltyPoints({ - customer_id: customerId, - points, - }) - } -} -``` - -You add an `addPoints` method that accepts two parameters: the ID of the customer and the points to add. - -In the method, you retrieve the customer's existing loyalty points using the `listLoyaltyPoints` method, which is automatically generated by the `MedusaService`. If the customer has existing points, you update them with the new points using the `updateLoyaltyPoints` method. - -Otherwise, if the customer doesn't have existing loyalty points, you create a new record with the `createLoyaltyPoints` method. - -The next method you'll add deducts points from the customer's loyalty points, which is useful when the customer redeems points. Add the following method to the `LoyaltyModuleService`: - -```ts title="src/modules/loyalty/service.ts" -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - // ... - async deductPoints(customerId: string, points: number): Promise { - const existingPoints = await this.listLoyaltyPoints({ - customer_id: customerId, - }) - - if (existingPoints.length === 0 || existingPoints[0].points < points) { - throw new MedusaError( - MedusaError.Types.NOT_ALLOWED, - "Insufficient loyalty points" - ) - } - - return await this.updateLoyaltyPoints({ - id: existingPoints[0].id, - points: existingPoints[0].points - points, - }) - } -} -``` - -The `deductPoints` method accepts the customer ID and the points to deduct. - -In the method, you retrieve the customer's existing loyalty points using the `listLoyaltyPoints` method. If the customer doesn't have existing points or if the points to deduct are greater than the existing points, you throw an error. - -Otherwise, you update the customer's loyalty points with the new value using the `updateLoyaltyPoints` method, which is automatically generated by `MedusaService`. - -Next, you'll add the method that retrieves the points of a customer. Add the following method to the `LoyaltyModuleService`: - -```ts title="src/modules/loyalty/service.ts" -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - // ... - async getPoints(customerId: string): Promise { - const points = await this.listLoyaltyPoints({ - customer_id: customerId, - }) - - return points[0]?.points || 0 - } -} -``` - -The `getPoints` method accepts the customer ID and retrieves the customer's loyalty points using the `listLoyaltyPoints` method. If the customer has no points, it returns `0`. - -#### Add Method to Map Points to Discount - -Finally, you'll add a method that implements the logic of mapping loyalty points to a discount amount. This is useful when the customer wants to redeem their points during checkout. - -The mapping logic may differ for each use case. For example, you may need to use a third-party service to map the loyalty points discount amount, or use some custom calculation. - -To simplify the logic in this tutorial, you'll use a simple calculation that maps 1 point to 1 currency unit. For example, `100` points = `$100` discount. - -Add the following method to the `LoyaltyModuleService`: - -```ts title="src/modules/loyalty/service.ts" -class LoyaltyModuleService extends MedusaService({ - LoyaltyPoint, -}) { - // ... - async calculatePointsFromAmount(amount: number): Promise { - // Convert amount to points using a standard conversion rate - // For example, $1 = 1 point - // Round down to nearest whole point - const points = Math.floor(amount) - - if (points < 0) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Amount cannot be negative" - ) - } - - return points - } -} -``` - -The `calculatePointsFromAmount` method accepts the amount and converts it to the nearest whole number of points. If the amount is negative, it throws an error. - -You'll use this method later to calculate the amount discounted when a customer redeems their loyalty points. - -### Export Module Definition - -The final piece to a module is its definition, which you export in an `index.ts` file at its root directory. This definition tells Medusa the name of the module and its service. - -So, create the file `src/modules/loyalty/index.ts` with the following content: - -```ts title="src/modules/loyalty/index.ts" -import { Module } from "@medusajs/framework/utils" -import LoyaltyModuleService from "./service" - -export const LOYALTY_MODULE = "loyalty" - -export default Module(LOYALTY_MODULE, { - service: LoyaltyModuleService, -}) -``` - -You use the `Module` function from the Modules SDK to create the module's definition. It accepts two parameters: - -1. The module's name, which is `loyalty`. -2. An object with a required property `service` indicating the module's service. - -You also export the module's name as `LOYALTY_MODULE` so you can reference it later. - -### Add Module to Medusa's Configurations - -Once you finish building the module, add it to Medusa's configurations to start using it. - -In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: - -```ts title="medusa-config.ts" -module.exports = defineConfig({ - // ... - modules: [ - { - resolve: "./src/modules/loyalty", - }, - ], -}) -``` - -Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. - -### Generate Migrations - -Since data models represent tables in the database, you define how they're created in the database with migrations. A migration is a TypeScript or JavaScript file that defines database changes made by a module. - -Refer to the [Migrations documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#5-generate-migrations/index.html.md) to learn more. - -Medusa's CLI tool can generate the migrations for you. To generate a migration for the Loyalty Module, run the following command in your Medusa application's directory: - -```bash -npx medusa db:generate loyalty -``` - -The `db:generate` command of the Medusa CLI accepts the name of the module to generate the migration for. You'll now have a `migrations` directory under `src/modules/loyalty` that holds the generated migration. - -Then, to reflect these migrations on the database, run the following command: - -```bash -npx medusa db:migrate -``` - -The table for the `LoyaltyPoint` data model is now created in the database. - -*** - -## Step 3: Change Loyalty Points Flow - -Now that you have a module that stores and manages loyalty points in the database, you'll start building flows around it that allow customers to earn and redeem points. - -The first flow you'll build will either add points to a customer's loyalty points or deduct them based on a purchased order. If the customer hasn't redeemed points, the points are added to their loyalty points. Otherwise, the points are deducted from their loyalty points. - -To build custom commerce features in Medusa, you create a [workflow](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in an endpoint. - -In this section, you'll build the workflow that adds or deducts loyalty points for an order's customer. Later, you'll execute this workflow when an order is placed. - -Learn more about workflows in the [Workflows documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). - -The workflow will have the following steps: - -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the order's details. -- [validateCustomerExistsStep](#validateCustomerExistsStep): Validate that the customer is registered. -- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. - -Medusa provides the `useQueryGraphStep` and `updatePromotionsStep` in its `@medusajs/medusa/core-flows` package. So, you'll only implement the other steps. - -### validateCustomerExistsStep - -In the workflow, you first need to validate that the customer is registered. Only registered customers can earn and redeem loyalty points. - -To do this, create the file `src/workflows/steps/validate-customer-exists.ts` with the following content: - -```ts title="src/workflows/steps/validate-customer-exists.ts" -import { CustomerDTO } from "@medusajs/framework/types" -import { createStep } from "@medusajs/framework/workflows-sdk" -import { MedusaError } from "@medusajs/framework/utils" - -export type ValidateCustomerExistsStepInput = { - customer: CustomerDTO | null | undefined -} - -export const validateCustomerExistsStep = createStep( - "validate-customer-exists", - async ({ customer }: ValidateCustomerExistsStepInput) => { - if (!customer) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Customer not found" - ) - } - - if (!customer.has_account) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Customer must have an account to earn or manage points" - ) - } - } -) -``` - -You create a step with `createStep` from the Workflows SDK. It accepts two parameters: - -1. The step's unique name, which is `validate-customer-exists`. -2. An async function that receives two parameters: - - The step's input, which is in this case an object with the customer's details. - - An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. - -In the step function, you validate that the customer is defined and that it's registered based on its `has_account` property. Otherwise, you throw an error. - -### getCartLoyaltyPromoStep - -Next, you'll need to retrieve the loyalty promotion applied on the cart, if there's any. This is useful to determine whether the customer has redeemed points. - -Before you create a step, you'll create a utility function that the step uses to retrieve the loyalty promotion of a cart. You'll create it as a separate utility function to use it later in other customizations. - -Create the file `src/utils/promo.ts` with the following content: - -```ts title="src/utils/promo.ts" -import { PromotionDTO, CustomerDTO, CartDTO } from "@medusajs/framework/types" - -export type CartData = CartDTO & { - promotions?: PromotionDTO[] - customer?: CustomerDTO - metadata: { - loyalty_promo_id?: string - } -} - -export function getCartLoyaltyPromotion( - cart: CartData -): PromotionDTO | undefined { - if (!cart?.metadata?.loyalty_promo_id) { - return - } - - return cart.promotions?.find( - (promotion) => promotion.id === cart.metadata.loyalty_promo_id - ) -} -``` - -You create a `getCartLoyaltyPromotion` function that accepts the cart's details as an input and returns the loyalty promotion if it exists. You retrieve the loyalty promotion if its ID is stored in the cart's `metadata.loyalty_promo_id` property. - -You can now create the step that uses this utility to retrieve a carts loyalty points promotion. To create the step, create the file `src/workflows/steps/get-cart-loyalty-promo.ts` with the following content: - -```ts title="src/workflows/steps/get-cart-loyalty-promo.ts" -import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" -import { CartData, getCartLoyaltyPromotion } from "../../utils/promo" -import { MedusaError } from "@medusajs/framework/utils" - -type GetCartLoyaltyPromoStepInput = { - cart: CartData, - throwErrorOn?: "found" | "not-found" -} - -export const getCartLoyaltyPromoStep = createStep( - "get-cart-loyalty-promo", - async ({ cart, throwErrorOn }: GetCartLoyaltyPromoStepInput) => { - const loyaltyPromo = getCartLoyaltyPromotion(cart) - - if (throwErrorOn === "found" && loyaltyPromo) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Loyalty promotion already applied to cart" - ) - } else if (throwErrorOn === "not-found" && !loyaltyPromo) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "No loyalty promotion found on cart" - ) - } - - return new StepResponse(loyaltyPromo) - } -) -``` - -You create a step that accepts an object having the following properties: - -- `cart`: The cart's details. -- `throwErrorOn`: An optional property that indicates whether to throw an error if the loyalty promotion is found or not found. - -The `throwErrorOn` property is useful to make the step reusable in different scenarios, allowing you to use it in later workflows. - -In the step, you call the `getCartLoyaltyPromotion` utility to retrieve the loyalty promotion. If the `throwErrorOn` property is set to `found` and the loyalty promotion is found, you throw an error. - -Otherwise, if the `throwErrorOn` property is set to `not-found` and the loyalty promotion is not found, you throw an error. - -To return data from a step, you return an instance of `StepResponse` from the Workflows SDK. It accepts as a parameter the data to return, which is the loyalty promotion in this case. - -### deductPurchasePointsStep - -If the order's cart has a loyalty promotion, you need to deduct points from the customer's loyalty points. To do this, create the file `src/workflows/steps/deduct-purchase-points.ts` with the following content: - -```ts title="src/workflows/steps/deduct-purchase-points.ts" highlights={deductStepHighlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { LOYALTY_MODULE } from "../../modules/loyalty" -import LoyaltyModuleService from "../../modules/loyalty/service" - -type DeductPurchasePointsInput = { - customer_id: string - amount: number -} - -export const deductPurchasePointsStep = createStep( - "deduct-purchase-points", - async ({ - customer_id, amount, - }: DeductPurchasePointsInput, { container }) => { - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - const pointsToDeduct = await loyaltyModuleService.calculatePointsFromAmount( - amount - ) - - const result = await loyaltyModuleService.deductPoints( - customer_id, - pointsToDeduct - ) - - return new StepResponse(result, { - customer_id, - points: pointsToDeduct, - }) - }, - async (data, { container }) => { - if (!data) { - return - } - - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - // Restore points in case of failure - await loyaltyModuleService.addPoints( - data.customer_id, - data.points - ) - } -) -``` - -You create a step that accepts an object having the following properties: - -- `customer_id`: The ID of the customer to deduct points from. -- `amount`: The promotion's amount, which will be used to calculate the points to deduct. - -In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you use the `calculatePointsFromAmount` method to calculate the points to deduct from the promotion's amount. - -After that, you call the `deductPoints` method to deduct the points from the customer's loyalty points. - -Finally, you return a `StepResponse` with the result of the `deductPoints`. - -#### Compensation Function - -This step has a compensation function, which is passed as a third parameter to the `createStep` function. - -The compensation function undoes the actions performed in a step. Then, if an error occurs during the workflow's execution, the compensation functions of executed steps are called to roll back the changes. This mechanism ensures data consistency in your application, especially as you integrate external systems. - -The compensation function accepts two parameters: - -1. Data passed from the step function to the compensation function. The data is passed as a second parameter of the returned `StepResponse` instance. -2. An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). - -In the compensation function, you resolve the Loyalty Module's service from the Medusa container. Then, you call the `addPoints` method to restore the points deducted from the customer's loyalty points if an error occurs. - -### addPurchaseAsPointsStep - -The last step you'll create adds points to the customer's loyalty points. You'll use this step if the customer didn't redeem points during checkout. - -To create the step, create the file `src/workflows/steps/add-purchase-as-points.ts` with the following content: - -```ts title="src/workflows/steps/add-purchase-as-points.ts" highlights={addPointsHighlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" -import { - createStep, - StepResponse, -} from "@medusajs/framework/workflows-sdk" -import { LOYALTY_MODULE } from "../../modules/loyalty" -import LoyaltyModuleService from "../../modules/loyalty/service" - -type StepInput = { - customer_id: string - amount: number -} - -export const addPurchaseAsPointsStep = createStep( - "add-purchase-as-points", - async (input: StepInput, { container }) => { - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - const pointsToAdd = await loyaltyModuleService.calculatePointsFromAmount( - input.amount - ) - - const result = await loyaltyModuleService.addPoints( - input.customer_id, - pointsToAdd - ) - - return new StepResponse(result, { - customer_id: input.customer_id, - points: pointsToAdd, - }) - }, - async (data, { container }) => { - if (!data) { - return - } - - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - await loyaltyModuleService.deductPoints( - data.customer_id, - data.points - ) - } -) -``` - -You create a step that accepts an object having the following properties: - -- `customer_id`: The ID of the customer to add points to. -- `amount`: The order's amount, which will be used to calculate the points to add. - -In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you use the `calculatePointsFromAmount` method to calculate the points to add from the order's amount. - -After that, you call the `addPoints` method to add the points to the customer's loyalty points. - -Finally, you return a `StepResponse` with the result of the `addPoints`. - -You also pass to the compensation function the customer's ID and the points added. In the compensation function, you deduct the points if an error occurs. - -### Add Utility Functions - -Before you create the workflow, you need a utility function that checks whether an order's cart has a loyalty promotion. This is useful to determine whether the customer redeemed points during checkout, allowing you to decide which steps to execute. - -To add the utility function, add the following to `src/utils/promo.ts`: - -```ts title="src/utils/promo.ts" -import { OrderDTO } from "@medusajs/framework/types" - -export type OrderData = OrderDTO & { - promotion?: PromotionDTO[] - customer?: CustomerDTO - cart?: CartData -} - -export const CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE = "customer_id" - -export function orderHasLoyaltyPromotion(order: OrderData): boolean { - const loyaltyPromotion = getCartLoyaltyPromotion( - order.cart as unknown as CartData - ) - - return loyaltyPromotion?.rules?.some((rule) => { - return rule?.attribute === CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE && ( - rule?.values?.some((value) => value.value === order.customer?.id) || false - ) - }) || false -} -``` - -You first define an `OrderData` type that extends the `OrderDTO` type. This type has the order's details, including the cart, customer, and promotions details. - -Then, you define a constant `CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE` that represents the attribute used in the promotion rule to check whether the customer ID is valid. - -Finally, you create the `orderHasLoyaltyPromotion` function that accepts an order's details and checks whether it has a loyalty promotion. It returns `true` if: - -- The order's cart has a loyalty promotion. You use the `getCartLoyaltyPromotion` utility to try to retrieve the loyalty promotion. -- The promotion's rules include the `customer_id` attribute and its value matches the order's customer ID. - - When you create the promotion for the cart later, you'll see how to set this rule. - -You'll use this utility in the workflow next. - -### Create the Workflow - -Now that you have all the steps, you can create the workflow that uses them. - -To create the workflow, create the file `src/workflows/handle-order-points.ts` with the following content: - -```ts title="src/workflows/handle-order-points.ts" highlights={handleOrderPointsHighlights} collapsibleLines="1-9" expandButtonLabel="Show Imports" -import { createWorkflow, when } from "@medusajs/framework/workflows-sdk" -import { updatePromotionsStep, useQueryGraphStep } from "@medusajs/medusa/core-flows" -import { validateCustomerExistsStep, ValidateCustomerExistsStepInput } from "./steps/validate-customer-exists" -import { deductPurchasePointsStep } from "./steps/deduct-purchase-points" -import { addPurchaseAsPointsStep } from "./steps/add-purchase-as-points" -import { OrderData, CartData } from "../utils/promo" -import { orderHasLoyaltyPromotion } from "../utils/promo" -import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" - -type WorkflowInput = { - order_id: string -} - -export const handleOrderPointsWorkflow = createWorkflow( - "handle-order-points", - ({ order_id }: WorkflowInput) => { - // @ts-ignore - const { data: orders } = useQueryGraphStep({ - entity: "order", - fields: [ - "id", - "customer.*", - "total", - "cart.*", - "cart.promotions.*", - "cart.promotions.rules.*", - "cart.promotions.rules.values.*", - "cart.promotions.application_method.*", - ], - filters: { - id: order_id, - }, - options: { - throwIfKeyNotFound: true, - }, - }) - - validateCustomerExistsStep({ - customer: orders[0].customer, - } as ValidateCustomerExistsStepInput) - - const loyaltyPointsPromotion = getCartLoyaltyPromoStep({ - cart: orders[0].cart as unknown as CartData, - }) - - when(orders, (orders) => - orderHasLoyaltyPromotion(orders[0] as unknown as OrderData) && - loyaltyPointsPromotion !== undefined - ) - .then(() => { - deductPurchasePointsStep({ - customer_id: orders[0].customer!.id, - amount: loyaltyPointsPromotion.application_method!.value as number, - }) - - updatePromotionsStep([ - { - id: loyaltyPointsPromotion.id, - status: "inactive", - }, - ]) - }) - - - when( - orders, - (order) => !orderHasLoyaltyPromotion(order[0] as unknown as OrderData) - ) - .then(() => { - addPurchaseAsPointsStep({ - customer_id: orders[0].customer!.id, - amount: orders[0].total, - }) - }) - } -) -``` - -You create a workflow using `createWorkflow` from the Workflows SDK. It accepts the workflow's unique name as a first parameter. - -It accepts as a second parameter a constructor function, which is the workflow's implementation. The function can accept input, which in this case is an object with the order's ID. - -In the workflow's constructor function, you: - -- Use `useQueryGraphStep` to retrieve the order's details. You pass the order's ID as a filter to retrieve the order. - - This step uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), which is a tool that retrieves data across modules. -- Validate that the customer is registered using the `validateCustomerExistsStep`. -- Retrieve the cart's loyalty promotion using the `getCartLoyaltyPromoStep`. -- Use `when` to check whether the order's cart has a loyalty promotion. - - Since you can't perform data manipulation in a workflow's constructor function, `when` allows you to perform steps if a condition is satisfied. - - You pass as a first parameter the object to perform the condition on, which is the order in this case. In the second parameter, you pass a function that returns a boolean value, indicating whether the condition is satisfied. - - To specify the steps to perform if a condition is satisfied, you chain a `then` method to the `when` method. You can perform any step within the `then` method. - - In this case, if the order's cart has a loyalty promotion, you call the `deductPurchasePointsStep` to deduct points from the customer's loyalty points. You also call the `updatePromotionsStep` to deactivate the cart's loyalty promotion. -- You use another `when` to check whether the order's cart doesn't have a loyalty promotion. - - If the condition is satisfied, you call the `addPurchaseAsPointsStep` to add points to the customer's loyalty points. - -You'll use this workflow next when an order is placed. - -To learn more about the constraints on a workflow's constructor function, refer to the [Workflow Constraints](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md) documentation. Refer to the [When-Then](https://docs.medusajs.com/docs/learn/fundamentals/workflows/conditions/index.html.md) documentation to learn more about the `when` method and how to use it in a workflow. - -*** - -## Step 4: Handle Order Placed Event - -Now that you have the workflow that handles adding or deducting loyalty points for an order, you need to execute it when an order is placed. - -Medusa has an event system that allows you to listen to events emitted by the Medusa server using a [subscriber](https://docs.medusajs.com/docs//learn/fundamentals/events-and-subscribers/index.html.md). A subscriber is an asynchronous function that's executed when its associated event is emitted. In a subscriber, you can execute a workflow that performs actions in result of the event. - -In this step, you'll create a subscriber that listens to the `order.placed` event and executes the `handleOrderPointsWorkflow` workflow. - -Refer to the [Events and Subscribers](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md) documentation to learn more. - -Subscribers are created in a TypeScript or JavaScript file under the `src/subscribers` directory. So, to create a subscriber, create the fle `src/subscribers/order-placed.ts` with the following content: - -```ts title="src/subscribers/order-placed.ts" -import type { - SubscriberArgs, - SubscriberConfig, -} from "@medusajs/framework" -import { handleOrderPointsWorkflow } from "../workflows/handle-order-points" - -export default async function orderPlacedHandler({ - event: { data }, - container, -}: SubscriberArgs<{ id: string }>) { - await handleOrderPointsWorkflow(container).run({ - input: { - order_id: data.id, - }, - }) -} - -export const config: SubscriberConfig = { - event: "order.placed", -} -``` - -The subscriber file must export: - -- An asynchronous subscriber function that's executed whenever the associated event, which is `order.placed` is triggered. -- A configuration object with an event property whose value is the event the subscriber is listening to. You can also pass an array of event names to listen to multiple events in the same subscriber. - -The subscriber function accepts an object with the following properties: - -- `event`: An object with the event's data payload. For example, the `order.placed` event has the order's ID in its data payload. -- `container`: The Medusa container, which you can use to resolve services and tools. - -In the subscriber function, you execute the `handleOrderPointsWorkflow` by invoking it, passing it the Medusa container, then using its `run` method, passing it the workflow's input. - -Whenever an order is placed now, the subscriber will be executed, which in turn will execute the workflow that handles the loyalty points flow. - -### Test it Out - -To test out the loyalty points flow, you'll use the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) that you installed in the first step. As mentioned in that step, the storefront will be installed in a separate directory from the Medusa application, and its name is `{project-name}-storefront`, where `{project-name}` is the name of your Medusa application's directory. - -So, run the following command in the Medusa application's directory to start the Medusa server: - -```bash title="Medusa Application" -npm run dev -``` - -Then, run the following command in the Next.js Starter Storefront's directory to start the Next.js server: - -```bash title="Next.js Starter Storefront" -npm run dev -``` - -The Next.js Starter Storefront will be running on `http://localhost:8000`, and the Medusa server will be running on `http://localhost:9000`. - -Open the Next.js Starter Storefront in your browser and create a new account by going to Account at the top right. - -Once you're logged in, add an item to the cart and go through the checkout flow. - -After you place the order, you'll see the following message in your Medusa application's terminal: - -```bash -info: Processing order.placed which has 1 subscribers -``` - -This message indicates that the `order.placed` event was emitted, and that your subscriber was executed. - -Since you didn't redeem any points during checkout, loyalty points will be added to your account. You'll implement an API route that allows you to retrieve the loyalty points in the next step. - -*** - -## Step 5: Retrieve Loyalty Points API Route - -Next, you want to allow customers to view their loyalty points. You can show them on their profile page, or during checkout. - -To expose a feature to clients, you create an [API route](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. - -You'll create an API route at the path `/store/customers/me/loyalty-points` that returns the loyalty points of the authenticated customer. - -Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). - -An API route is created in a `route.ts` file under a sub-directory of the `src/api` directory. The path of the API route is the file's path relative to `src/api`. - -So, to create an API route at the path `/store/customers/me/loyalty-points`, create the file `src/api/store/customers/me/loyalty-points/route.ts` with the following content: - -```ts title="src/api/store/customers/me/loyalty-points/route.ts" - -import { - AuthenticatedMedusaRequest, - MedusaResponse, -} from "@medusajs/framework/http" -import { LOYALTY_MODULE } from "../../../../../modules/loyalty" -import LoyaltyModuleService from "../../../../../modules/loyalty/service" - -export async function GET( - req: AuthenticatedMedusaRequest, - res: MedusaResponse -) { - const loyaltyModuleService: LoyaltyModuleService = req.scope.resolve( - LOYALTY_MODULE - ) - - const points = await loyaltyModuleService.getPoints( - req.auth_context.actor_id - ) - - res.json({ - points, - }) -} -``` - -Since you export a `GET` route handler function, you're exposing a `GET` endpoint at `/store/customers/me/loyalty-points`. The route handler function accepts two parameters: - -1. A request object with details and context on the request, such as body parameters or authenticated customer details. -2. A response object to manipulate and send the response. - -In the route handler, you resolve the Loyalty Module's service from the Medusa container (which is available at `req.scope`). - -Then, you call the service's `getPoints` method to retrieve the authenticated customer's loyalty points. Note that routes starting with `/store/customers/me` are only accessible by authenticated customers. You can access the authenticated customer ID from the request's context, which is available at `req.auth_context.actor_id`. - -Finally, you return the loyalty points in the response. - -You'll test out this route as you customize the Next.js Starter Storefront next. - -*** - -## Step 6: Show Loyalty Points During Checkout - -Now that you have the API route to retrieve the loyalty points, you can show them during checkout. - -In this step, you'll customize the Next.js Starter Storefront to show the loyalty points in the checkout page. - -First, you'll add a server action function that retrieves the loyalty points from the route you created earlier. In `src/lib/data/customer.ts`, add the following function: - -```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" -export const getLoyaltyPoints = async () => { - const headers = { - ...(await getAuthHeaders()), - } - - return sdk.client.fetch<{ points: number }>( - `/store/customers/me/loyalty-points`, - { - method: "GET", - headers, - } - ) - .then(({ points }) => points) - .catch(() => null) -} -``` - -You add a `getLoyaltyPoints` function that retrieves the authenticated customer's loyalty points from the API route you created earlier. You pass the authentication headers using the `getAuthHeaders` function, which is a utility function defined in the Next.js Starter Storefront. - -If the customer isn't authenticated, the request will fail. So, you catch the error and return `null` in that case. - -Next, you'll create a component that shows the loyalty points in the checkout page. Create the file `src/modules/checkout/components/loyalty-points/index.tsx` with the following content: - -```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={loyaltyPointsHighlights} -"use client" - -import { HttpTypes } from "@medusajs/types" -import { useEffect, useMemo, useState } from "react" -import { getLoyaltyPoints } from "../../../../lib/data/customer" -import { Button, Heading } from "@medusajs/ui" -import Link from "next/link" - -type LoyaltyPointsProps = { - cart: HttpTypes.StoreCart & { - promotions: HttpTypes.StorePromotion[] - } -} - -const LoyaltyPoints = ({ cart }: LoyaltyPointsProps) => { - const isLoyaltyPointsPromoApplied = useMemo(() => { - return cart.promotions.find( - (promo) => promo.id === cart.metadata?.loyalty_promo_id - ) !== undefined - }, [cart]) - const [loyaltyPoints, setLoyaltyPoints] = useState< - number | null - >(null) - - useEffect(() => { - getLoyaltyPoints() - .then((points) => { - console.log(points) - setLoyaltyPoints(points) - }) - }, []) - - const handleTogglePromotion = async ( - e: React.MouseEvent - ) => { - e.preventDefault() - // TODO apply or remove loyalty promotion - } - - return ( - <> -
-
- - Loyalty Points - - {loyaltyPoints === null && ( - - Sign up to get and use loyalty points - - )} - {loyaltyPoints !== null && ( -
- - - You have {loyaltyPoints} loyalty points - -
- )} -
- - ) -} - -export default LoyaltyPoints -``` - -You create a `LoyaltyPoints` component that accepts the cart's details as a prop. In the component, you: - -- Create a `isLoyaltyPointsPromoApplied` memoized value that checks whether the cart has a loyalty promotion applied. You use the `cart.metadata.loyalty_promo_id` property to check this. -- Create a `loyaltyPoints` state to store the customer's loyalty points. -- Call the `getLoyaltyPoints` function in a `useEffect` hook to retrieve the loyalty points from the API route you created earlier. You set the `loyaltyPoints` state with the retrieved points. -- Define `handleTogglePromotion` that, when clicked, would either apply or remove the promotion. You'll implement these functionalities later. -- Render the loyalty points in the component. If the customer isn't authenticated, you show a link to the account page to sign up. Otherwise, you show the loyalty points and a button to apply or remove the promotion. - -Next, you'll show this component at the end of the checkout's summary component. So, import the component in `src/modules/checkout/templates/checkout-summary/index.tsx`: - -```tsx title="src/modules/checkout/templates/checkout-summary/index.tsx" badgeLabel="Storefront" badgeColor="blue" -import LoyaltyPoints from "../../components/loyalty-points" -``` - -Then, in the return statement of the `CheckoutSummary` component, add the following after the `div` wrapping the `DiscountCode`: - -```tsx title="src/modules/checkout/templates/checkout-summary/index.tsx" badgeLabel="Storefront" badgeColor="blue" - -``` - -This will show the loyalty points component at the end of the checkout summary. - -### Test it Out - -To test out the customizations to the checkout flow, make sure both the Medusa application and Next.js Starter Storefront are running. - -Then, as an authenticated customer, add an item to cart and proceed to checkout. You'll find a new "Loyalty Points" section at the end of the checkout summary. - -![Loyalty Points Section at the end of the summary section at the right](https://res.cloudinary.com/dza7lstvk/image/upload/v1744195223/Medusa%20Resources/Screenshot_2025-04-09_at_1.39.34_PM_l5oltc.png) - -If you made a purchase before, you can see your loyalty points. You'll also see the "Apply Loyalty Points" button, which doesn't yet do anything. You'll add the functionality next. - -*** - -## Step 7: Apply Loyalty Points to Cart - -The next feature you'll implement allows the customer to apply their loyalty points during checkout. To implement the feature, you need: - -- A workflow that implements the steps of the apply loyalty points flow. -- An API route that exposes the workflow's functionality to clients. You'll then send a request to this API route to apply the loyalty points on the customer's cart. -- A function in the Next.js Starter Storefront that sends the request to the API route you created earlier. - -The workflow will have the following steps: - -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details. -- [validateCustomerExistsStep](#validateCustomerExistsStep): Validate that the customer is registered. -- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. -- [getCartLoyaltyPromoAmountStep](#getCartLoyaltyPromoAmountStep): Get the amount to be discounted based on the loyalty points. -- [createPromotionsStep](https://docs.medusajs.com/references/medusa-workflows/steps/createPromotionsStep/index.html.md): Create a new loyalty promotion for the cart. -- [updateCartPromotionsWorkflow](https://docs.medusajs.com/references/medusa-workflows/workflows/updateCartPromotionsWorkflow/index.html.md): Update the cart's promotions with the new loyalty promotion. -- [updateCartsStep](https://docs.medusajs.com/references/medusa-workflows/steps/updateCartsStep/index.html.md): Update the cart to store the ID of the loyalty promotion in the metadata. -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details again. - -Most of the workflow's steps are either provided by Medusa in the `@medusajs/medusa/core-flows` package or steps you've already implemented. You only need to implement the `getCartLoyaltyPromoAmountStep` step. - -### getCartLoyaltyPromoAmountStep - -The fourth step in the workflow is the `getCartLoyaltyPromoAmountStep`, which retrieves the amount to be discounted based on the loyalty points. This step is useful to determine how much discount to apply to the cart. - -To create the step, create the file `src/workflows/steps/get-cart-loyalty-promo-amount.ts` with the following content: - -```ts title="src/workflows/steps/get-cart-loyalty-promo-amount.ts" highlights={getCartLoyaltyPromoAmountStepHighlights} -import { PromotionDTO, CustomerDTO } from "@medusajs/framework/types" -import { MedusaError } from "@medusajs/framework/utils" -import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" -import LoyaltyModuleService from "../../modules/loyalty/service" -import { LOYALTY_MODULE } from "../../modules/loyalty" - -export type GetCartLoyaltyPromoAmountStepInput = { - cart: { - id: string - customer: CustomerDTO - promotions?: PromotionDTO[] - total: number - } -} - -export const getCartLoyaltyPromoAmountStep = createStep( - "get-cart-loyalty-promo-amount", - async ({ cart }: GetCartLoyaltyPromoAmountStepInput, { container }) => { - // Check if customer has any loyalty points - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - const loyaltyPoints = await loyaltyModuleService.getPoints( - cart.customer.id - ) - - if (loyaltyPoints <= 0) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - "Customer has no loyalty points" - ) - } - - const pointsAmount = await loyaltyModuleService.calculatePointsFromAmount( - loyaltyPoints - ) - - const amount = Math.min(pointsAmount, cart.total) - - return new StepResponse(amount) - } -) -``` - -You create a step that accepts an object having the cart's details. - -In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you call the `getPoints` method to retrieve the customer's loyalty points. If the customer has no loyalty points, you throw an error. - -Next, you call the `calculatePointsFromAmount` method to calculate the amount to be discounted based on the loyalty points. You use the `Math.min` function to ensure that the amount doesn't exceed the cart's total. - -Finally, you return a `StepResponse` with the amount to be discounted. - -### Create the Workflow - -You can now create the workflow that applies a loyalty promotion to the cart. - -To create the workflow, create the file `src/workflows/apply-loyalty-on-cart.ts` with the following content: - -```ts title="src/workflows/apply-loyalty-on-cart.ts" highlights={applyLoyaltyOnCartWorkflowHighlights} collapsibleLines="1-24" expandButtonLabel="Show Imports" -import { - createWorkflow, - transform, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { - createPromotionsStep, - updateCartPromotionsWorkflow, - updateCartsStep, - useQueryGraphStep, -} from "@medusajs/medusa/core-flows" -import { - validateCustomerExistsStep, - ValidateCustomerExistsStepInput, -} from "./steps/validate-customer-exists" -import { - getCartLoyaltyPromoAmountStep, - GetCartLoyaltyPromoAmountStepInput, -} from "./steps/get-cart-loyalty-promo-amount" -import { CartData, CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE } from "../utils/promo" -import { CreatePromotionDTO } from "@medusajs/framework/types" -import { PromotionActions } from "@medusajs/framework/utils" -import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" - -type WorkflowInput = { - cart_id: string -} - -const fields = [ - "id", - "customer.*", - "promotions.*", - "promotions.application_method.*", - "promotions.rules.*", - "promotions.rules.values.*", - "currency_code", - "total", - "metadata", -] - -export const applyLoyaltyOnCartWorkflow = createWorkflow( - "apply-loyalty-on-cart", - (input: WorkflowInput) => { - // @ts-ignore - const { data: carts } = useQueryGraphStep({ - entity: "cart", - fields, - filters: { - id: input.cart_id, - }, - options: { - throwIfKeyNotFound: true, - }, - }) - - validateCustomerExistsStep({ - customer: carts[0].customer, - } as ValidateCustomerExistsStepInput) - - getCartLoyaltyPromoStep({ - cart: carts[0] as unknown as CartData, - throwErrorOn: "found", - }) - - const amount = getCartLoyaltyPromoAmountStep({ - cart: carts[0], - } as unknown as GetCartLoyaltyPromoAmountStepInput) - - // TODO create and apply the promotion on the cart - } -) -``` - -You create a workflow that accepts an object with the cart's ID as input. - -So far, you: - -- Use `useQueryGraphStep` to retrieve the cart's details. You pass the cart's ID as a filter to retrieve the cart. -- Validate that the customer is registered using the `validateCustomerExistsStep`. -- Check whether the cart has a loyalty promotion using the `getCartLoyaltyPromoStep`. You pass the `throwErrorOn` parameter with the value `found` to throw an error if a loyalty promotion is found in the cart. -- Retrieve the amount to be discounted based on the loyalty points using the `getCartLoyaltyPromoAmountStep`. - -Next, you need to create a new loyalty promotion for the cart. First, you'll prepare the data of the promotion to be created. - -Replace the `TODO` with the following: - -```ts title="src/workflows/apply-loyalty-on-cart.ts" highlights={prepareLoyaltyPromoDataHighlights} -const promoToCreate = transform({ - carts, - amount, -}, (data) => { - const randomStr = Math.random().toString(36).substring(2, 8) - const uniqueId = ( - "LOYALTY-" + data.carts[0].customer?.first_name + "-" + randomStr - ).toUpperCase() - return { - code: uniqueId, - type: "standard", - status: "active", - application_method: { - type: "fixed", - value: data.amount, - target_type: "order", - currency_code: data.carts[0].currency_code, - allocation: "across", - }, - rules: [ - { - attribute: CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE, - operator: "eq", - values: [data.carts[0].customer!.id], - }, - ], - campaign: { - name: uniqueId, - description: "Loyalty points promotion for " + data.carts[0].customer!.email, - campaign_identifier: uniqueId, - budget: { - type: "usage", - limit: 1, - }, - }, - } -}) - -// TODO create promotion and apply it on cart -``` - -Since data manipulation isn't allowed in a workflow constructor, you use the [transform](https://docs.medusajs.com/docs/learn/fundamentals/workflows/variable-manipulation/index.html.md) function from the Workflows SDK. It accepts two parameters: - -- The data to perform manipulation on. In this case, you pass the cart's details and the amount to be discounted. -- A function that receives the data from the first parameter, and returns the transformed data. - -In the transformation function, you prepare th data of the loyalty promotion to be created. Some key details include: - -- You set the discount amount in the application method of the promotion. -- You add a rule to the promotion that ensures it can be used only in carts having their `customer_id` equal to this customer's ID. This prevents other customers from using this promotion. -- You create a campaign for the promotion, and you set the campaign budget to a single usage. This prevents the customer from using the promotion again. - -Learn more about promotion concepts in the [Promotion Module](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/promotion/index.html.md)'s documentation. - -You can now use the returned data to create a promotion and apply it to the cart. Replace the new `TODO` with the following: - -```ts title="src/workflows/apply-loyalty-on-cart.ts" highlights={createLoyaltyPromoStepHighlights} -const loyaltyPromo = createPromotionsStep([ - promoToCreate, -] as CreatePromotionDTO[]) - -const { metadata, ...updatePromoData } = transform({ - carts, - promoToCreate, - loyaltyPromo, -}, (data) => { - const promos = [ - ...(data.carts[0].promotions?.map((promo) => promo?.code).filter(Boolean) || []) as string[], - data.promoToCreate.code, - ] - - return { - cart_id: data.carts[0].id, - promo_codes: promos, - action: PromotionActions.ADD, - metadata: { - loyalty_promo_id: data.loyaltyPromo[0].id, - }, - } -}) - -updateCartPromotionsWorkflow.runAsStep({ - input: updatePromoData, -}) - -updateCartsStep([ - { - id: input.cart_id, - metadata, - }, -]) - -// retrieve cart with updated promotions -// @ts-ignore -const { data: updatedCarts } = useQueryGraphStep({ - entity: "cart", - fields, - filters: { id: input.cart_id }, -}).config({ name: "retrieve-cart" }) - -return new WorkflowResponse(updatedCarts[0]) -``` - -In the rest of the workflow, you: - -- Create the loyalty promotion using the data you prepared earlier using the `createPromotionsStep`. -- Use the `transform` function to prepare the data to update the cart's promotions. You add the new loyalty promotion code to the cart's promotions codes, and set the `loyalty_promo_id` in the cart's metadata. -- Update the cart's promotions with the new loyalty promotion using the `updateCartPromotionsWorkflow` workflow. -- Update the cart's metadata with the loyalty promotion ID using the `updateCartsStep`. -- Retrieve the cart's details again using `useQueryGraphStep` to get the updated cart with the new loyalty promotion. - -To return data from the workflow, you must return an instance of `WorkflowResponse`. You pass it the data to be returned, which is in this case the cart's details. - -### Create the API Route - -Next, you'll create the API route that executes this workflow. - -To create the API route, create the file `src/api/store/carts/[id]/loyalty-points/route.ts` with the following content: - -```ts title="src/api/store/carts/[id]/loyalty-points/route.ts" -import { MedusaRequest, MedusaResponse } from "@medusajs/framework/http" -import { applyLoyaltyOnCartWorkflow } from "../../../../../workflows/apply-loyalty-on-cart" - -export async function POST( - req: MedusaRequest, - res: MedusaResponse -) { - const { id: cart_id } = req.params - - const { result: cart } = await applyLoyaltyOnCartWorkflow(req.scope) - .run({ - input: { - cart_id, - }, - }) - - res.json({ cart }) -} -``` - -Since you export a `POST` route handler, you expose a `POST` API route at `/store/carts/[id]/loyalty-points`. - -In the route handler, you execute the `applyLoyaltyOnCartWorkflow` workflow, passing it the cart ID as an input. You return the cart's details in the response. - -You can now use this API route in the Next.js Starter Storefront. - -### Apply Loyalty Points in the Storefront - -In the Next.js Starter Storefront, you need to add a server action function that sends a request to the API route you created earlier. Then, you'll use that function when the customer clicks the "Apply Loyalty Points" button. - -To add the function, add the following to `src/lib/data/cart.ts` in the Next.js Starter Storefront: - -```ts title="src/lib/data/cart.ts" badgeLabel="Storefront" badgeColor="blue" -export async function applyLoyaltyPointsOnCart() { - const cartId = await getCartId() - const headers = { - ...(await getAuthHeaders()), - } - - return await sdk.client.fetch<{ - cart: HttpTypes.StoreCart & { - promotions: HttpTypes.StorePromotion[] - } - }>(`/store/carts/${cartId}/loyalty-points`, { - method: "POST", - headers, - }) - .then(async (result) => { - const cartCacheTag = await getCacheTag("carts") - revalidateTag(cartCacheTag) - - return result - }) -} -``` - -You create an `applyLoyaltyPointsOnCart` function that sends a request to the API route you created earlier. - -In the function, you retrieve the cart ID stored in the cookie using the `getCartId` function, which is available in the Next.js Starter Storefront. - -Then, you send the request. Once the request is resolved successfully, you revalidate the cart cache tag to ensure that the cart's details are updated and refetched by other components. This ensures that the applied promotion is shown in the checkout summary without needing to refresh the page. - -Finally, you'll use this function in the `handleTogglePromotion` function in the `LoyaltyPoints` component you created earlier. - -At the top of `src/modules/checkout/components/loyalty-points/index.tsx`, import the function: - -```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" -import { applyLoyaltyPointsOnCart } from "../../../../lib/data/cart" -``` - -Then, replace the `handleTogglePromotion` function with the following: - -```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" -const handleTogglePromotion = async ( - e: React.MouseEvent -) => { - e.preventDefault() - if (!isLoyaltyPointsPromoApplied) { - await applyLoyaltyPointsOnCart() - } else { - // TODO remove loyalty points - } -} -``` - -In the `handleTogglePromotion` function, you call the `applyLoyaltyPointsOnCart` function if the cart doesn't have a loyalty promotion. This will send a request to the API route you created earlier, which will execute the workflow that applies the loyalty promotion to the cart. - -You'll implement removing the loyalty points promotion in a later step. - -### Test it Out - -To test out applying the loyalty points on the cart, start the Medusa application and Next.js Starter Storefront. - -Then, in the checkout flow as an authenticated customer, click on the "Apply Loyalty Points" button. The checkout summary will be updated with the applied promotion and the discount amount. - -If you don't want the promotion to be shown in the "Promotions(s) applied" section, you can filter the promotions in `src/modules/checkout/components/discount-code/index.tsx` to not show a promotion matching `cart.metadata.loyalty_promo_id`. - -![Discounted amount is shown as part of the summary and the promotion is shown as part of the applied promotions](https://res.cloudinary.com/dza7lstvk/image/upload/v1744200895/Medusa%20Resources/Screenshot_2025-04-09_at_3.14.19_PM_abmtjh.png) - -*** - -## Step 8: Remove Loyalty Points From Cart - -In this step, you'll implement the functionality to remove the loyalty points promotion from the cart. This is useful if the customer changes their mind and wants to remove the promotion. - -To implement this functionality, you'll need to: - -- Create a workflow that removes the loyalty points promotion from the cart. -- Create an API route that executes the workflow. -- Create a function in the Next.js Starter Storefront that sends a request to the API route you created earlier. -- Use the function in the `handleTogglePromotion` function in the `LoyaltyPoints` component you created earlier. - -### Create the Workflow - -The workflow will have the following steps: - -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details. -- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. -- [updateCartPromotionsWorkflow](https://docs.medusajs.com/references/medusa-workflows/workflows/updateCartPromotionsWorkflow/index.html.md): Update the cart's promotions to remove the loyalty promotion. -- [updateCartsStep](https://docs.medusajs.com/references/medusa-workflows/steps/updateCartsStep/index.html.md): Update the cart to remove the loyalty promotion ID from the metadata. -- [updatePromotionsStep](https://docs.medusajs.com/references/medusa-workflows/steps/updatePromotionsStep/index.html.md): Deactive the loyalty promotion. -- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the cart's details again. - -Since you already have all the steps, you can create the workflow. - -To create the workflow, create the file `src/workflows/remove-loyalty-from-cart.ts` with the following content: - -```ts title="src/workflows/remove-loyalty-from-cart.ts" collapsibleLines="1-15" expandButtonLabel="Show Imports" highlights={removeLoyaltyFromCartWorkflowHighlights} -import { - createWorkflow, - transform, - WorkflowResponse, -} from "@medusajs/framework/workflows-sdk" -import { - useQueryGraphStep, - updateCartPromotionsWorkflow, - updateCartsStep, - updatePromotionsStep, -} from "@medusajs/medusa/core-flows" -import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" -import { PromotionActions } from "@medusajs/framework/utils" -import { CartData } from "../utils/promo" - -type WorkflowInput = { - cart_id: string -} - -const fields = [ - "id", - "customer.*", - "promotions.*", - "promotions.application_method.*", - "promotions.rules.*", - "promotions.rules.values.*", - "currency_code", - "total", - "metadata", -] - -export const removeLoyaltyFromCartWorkflow = createWorkflow( - "remove-loyalty-from-cart", - (input: WorkflowInput) => { - // @ts-ignore - const { data: carts } = useQueryGraphStep({ - entity: "cart", - fields, - filters: { - id: input.cart_id, - }, - }) - - const loyaltyPromo = getCartLoyaltyPromoStep({ - cart: carts[0] as unknown as CartData, - throwErrorOn: "not-found", - }) - - updateCartPromotionsWorkflow.runAsStep({ - input: { - cart_id: input.cart_id, - promo_codes: [loyaltyPromo.code!], - action: PromotionActions.REMOVE, - }, - }) - - const newMetadata = transform({ - carts, - }, (data) => { - const { loyalty_promo_id, ...rest } = data.carts[0].metadata || {} - - return { - ...rest, - loyalty_promo_id: null, - } - }) - - updateCartsStep([ - { - id: input.cart_id, - metadata: newMetadata, - }, - ]) - - updatePromotionsStep([ - { - id: loyaltyPromo.id, - status: "inactive", - }, - ]) - - // retrieve cart with updated promotions - // @ts-ignore - const { data: updatedCarts } = useQueryGraphStep({ - entity: "cart", - fields, - filters: { id: input.cart_id }, - }).config({ name: "retrieve-cart" }) - - return new WorkflowResponse(updatedCarts[0]) - } -) -``` - -You create a workflow that accepts an object with the cart's ID as input. - -In the workflow, you: - -- Use `useQueryGraphStep` to retrieve the cart's details.

You pass the `throwErrorOn` parameter with the value `not-found` to throw an error if a loyalty promotion isn't found in the cart. -- Update the cart's promotions using the `updateCartPromotionsWorkflow`, removing the loyalty promotion. -- Use the `transform` function to prepare the new metadata of the cart. You remove the `loyalty_promo_id` from the metadata. -- Update the cart's metadata with the new metadata using the `updateCartsStep`. -- Deactivate the loyalty promotion using the `updatePromotionsStep`. -- Retrieve the cart's details again using `useQueryGraphStep` to get the updated cart with the new loyalty promotion. -- Return the cart's details in a `WorkflowResponse` instance. - -### Create the API Route - -Next, you'll create the API route that executes this workflow. - -To create the API route, add the following in `src/api/store/carts/[id]/loyalty-points/route.ts`: - -```ts title="src/api/store/carts/[id]/loyalty-points/route.ts" -// other imports... -import { removeLoyaltyFromCartWorkflow } from "../../../../../workflows/remove-loyalty-from-cart" - -// ... -export async function DELETE( - req: MedusaRequest, - res: MedusaResponse -) { - const { id: cart_id } = req.params - - const { result: cart } = await removeLoyaltyFromCartWorkflow(req.scope) - .run({ - input: { - cart_id, - }, - }) - - res.json({ cart }) -} -``` - -You export a `DELETE` route handler, which exposes a `DELETE` API route at `/store/carts/[id]/loyalty-points`. - -In the route handler, you execute the `removeLoyaltyFromCartWorkflow` workflow, passing it the cart ID as an input. You return the cart's details in the response. - -You can now use this API route in the Next.js Starter Storefront. - -### Remove Loyalty Points in the Storefront - -In the Next.js Starter Storefront, you need to add a server action function that sends a request to the API route you created earlier. Then, you'll use that function when the customer clicks the "Remove Loyalty Points" button, which shows when the cart has a loyalty promotion applied. - -To add the function, add the following to `src/lib/data/cart.ts`: - -```ts title="src/lib/data/cart.ts" badgeLabel="Storefront" badgeColor="blue" -export async function removeLoyaltyPointsOnCart() { - const cartId = await getCartId() - const headers = { - ...(await getAuthHeaders()), - } - const next = { - ...(await getCacheOptions("carts")), - } - - return await sdk.client.fetch<{ - cart: HttpTypes.StoreCart & { - promotions: HttpTypes.StorePromotion[] - } - }>(`/store/carts/${cartId}/loyalty-points`, { - method: "DELETE", - headers, - }) - .then(async (result) => { - const cartCacheTag = await getCacheTag("carts") - revalidateTag(cartCacheTag) - - return result - }) -} -``` - -You create a `removeLoyaltyPointsOnCart` function that sends a request to the API route you created earlier. - -In the function, you retrieve the cart ID stored in the cookie using the `getCartId` function, which is available in the Next.js Starter Storefront. - -Then, you send the request to the API route. Once the request is resolved successfully, you revalidate the cart cache tag to ensure that the cart's details are updated and refetched by other components. This ensures that the promotion is removed from the checkout summary without needing to refresh the page. - -Finally, you'll use this function in the `handleTogglePromotion` function in the `LoyaltyPoints` component you created earlier. - -At the top of `src/modules/checkout/components/loyalty-points/index.tsx`, add the following import: - -```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" -import { removeLoyaltyPointsOnCart } from "../../../../lib/data/cart" -``` - -Then, replace the `TODO` in `handleTogglePromotion` with the following: - -```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" -await removeLoyaltyPointsOnCart() -``` - -In the `handleTogglePromotion` function, you call the `removeLoyaltyPointsOnCart` function if the cart has a loyalty promotion. This will send a request to the API route you created earlier, which will execute the workflow that removes the loyalty promotion from the cart. - -### Test it Out - -To test out removing the loyalty points from the cart, start the Medusa application and Next.js Starter Storefront. - -Then, in the checkout flow as an authenticated customer, after applying the loyalty points, click on the "Remove Loyalty Points" button. The checkout summary will be updated with the removed promotion and the discount amount. - -![The "Remove Loyalty Points" button is shown in the "Loyalty Points" section](https://res.cloudinary.com/dza7lstvk/image/upload/v1744204436/Medusa%20Resources/Screenshot_2025-04-09_at_4.13.24_PM_xt5trh.png) - -*** - -## Step 9: Validate Loyalty Points on Cart Completion - -After the customer applies the loyalty points to the cart and places the order, you need to validate that the customer actually has the loyalty points. This prevents edge cases where the customer may have applied the loyalty points previously but they don't have them anymore. - -So, in this step, you'll hook into Medusa's cart completion flow to perform the validation. - -Since Medusa uses workflows in its API routes, it allows you to hook into them and perform custom functionalities using [Workflow Hooks](https://docs.medusajs.com/docs/learn/fundamentals/workflows/workflow-hooks/index.html.md). A workflow hook is a point in a workflow where you can inject custom functionality as a step function, called a hook handler. - -Medusa uses the [completeCartWorkflow](https://docs.medusajs.com/references/medusa-workflows/completeCartWorkflow/index.html.md) hook to complete the cart and place an order. This workflow has a `validate` hook that allows you to perform custom validation before the cart is completed. - -To consume the `validate` hook, create the file `src/workflows/hooks/complete-cart.ts` with the following content: - -```ts title="src/workflows/hooks/complete-cart.ts" highlights={completeCartWorkflowHookHighlights} collapsibleLines="1-6" expandButtonLabel="Show Imports" -import { completeCartWorkflow } from "@medusajs/medusa/core-flows" -import LoyaltyModuleService from "../../modules/loyalty/service" -import { LOYALTY_MODULE } from "../../modules/loyalty" -import { CartData, getCartLoyaltyPromotion } from "../../utils/promo" -import { MedusaError } from "@medusajs/framework/utils" - -completeCartWorkflow.hooks.validate( - async ({ cart }, { container }) => { - const query = container.resolve("query") - const loyaltyModuleService: LoyaltyModuleService = container.resolve( - LOYALTY_MODULE - ) - - const { data: carts } = await query.graph({ - entity: "cart", - fields: [ - "id", - "promotions.*", - "customer.*", - "promotions.rules.*", - "promotions.rules.values.*", - "promotions.application_method.*", - "metadata", - ], - filters: { - id: cart.id, - }, - }, { - throwIfKeyNotFound: true, - }) - - const loyaltyPromo = getCartLoyaltyPromotion( - carts[0] as unknown as CartData - ) - - if (!loyaltyPromo) { - return - } - - const customerLoyaltyPoints = await loyaltyModuleService.getPoints( - carts[0].customer!.id - ) - const requiredPoints = await loyaltyModuleService.calculatePointsFromAmount( - loyaltyPromo.application_method!.value as number - ) - - if (customerLoyaltyPoints < requiredPoints) { - throw new MedusaError( - MedusaError.Types.INVALID_DATA, - `Customer does not have enough loyalty points. Required: ${ - requiredPoints - }, Available: ${customerLoyaltyPoints}` - ) - } - } -) -``` - -Workflows have a special `hooks` property that includes all the hooks tht you can consume in that workflow. You consume the hook by invoking it from the workflow's `hooks` property. - -Since the hook is essentially a step function, it accepts the following parameters: - -- The hook's input passed from the workflow, which differs for each hook. The `validate` hook receives an object having the cart's details. -- The step context object, which contains the Medusa container. You can use it to resolve services and perform actions. - -In the hook, you resolve Query and the Loyalty Module's service. Then, you use Query to retrieve the cart's necessary details, including its promotions, customer, and metadata. - -After that, you retrieve the customer's loyalty points and calculate the required points to apply the loyalty promotion. - -If the customer doesn't have enough loyalty points, you throw an error. This will prevent the cart from being completed if the customer doesn't have enough loyalty points. - -*** - -## Test Out Cart Completion with Loyalty Points - -Since you now have the entire loyalty points flow implemented, you can test it out by going through the checkout flow, applying the loyalty points to the cart. - -When you place the order, if the customer has sufficient loyalty points, the validation hook will pass. - -Then, the `order.placed` event will be emitted, which will execute the subscriber that calls the `handleOrderPointsWorkflow`. - -In the workflow, since the order's cart has a loyalty promotion, the points equivalent to the promotion will be deducted, and the promotion becomes inactive. - -You can confirm that the loyalty points were deducted either by sending a request to the [retrieve loyalty points API route](#step-5-retrieve-loyalty-points-api-route), or by going through the checkout process again in the storefront. - -*** - -## Next Steps - -You've now implement a loyalty points system in Medusa. There's still more that you can implement based on your use case: - -- Add loyalty points on registration or other events. Refer to the [Events Reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/events-reference/index.html.md) for a full list of available events you can listen to. -- Show the customer their loyalty point usage history. This will require adding another data model in the Loyalty Module that records the usage history. You can create records of that data model when an order that has a loyalty promotion is placed, then customize the storefront to show a new page for loyalty points history. -- Customize the Medusa Admin to show a new page or [UI Route](https://docs.medusajs.com/docs/learn/fundamentals/admin/ui-routes/index.html.md) for loyalty points information and analytics. - -If you're new to Medusa, check out the [main documentation](https://docs.medusajs.com/docs/learn/index.html.md), where you'll get a more in-depth learning of all the concepts you've used in this guide and more. - -To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). - - # Implement Product Reviews in Medusa In this tutorial, you'll learn how to implement product reviews in Medusa. @@ -44282,6 +42596,1797 @@ If you're new to Medusa, check out the [main documentation](https://docs.medusaj To learn more about the commerce features that Medusa provides, check out Medusa's [Commerce Modules](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/index.html.md). +# Implement Loyalty Points System in Medusa + +In this tutorial, you'll learn how to implement a loyalty points system in Medusa. + +Medusa Cloud provides a beta Store Credits feature that facilitates building a loyalty point system.

A module is a reusable package with functionalities related to a single feature or domain. Medusa integrates the module into your application without implications or side effects on your setup. + +In the module, you define the data models necessary for a feature and the logic to manage these data models. Later, you can build commerce flows around your module. + +In this step, you'll build a Loyalty Module that defines the necessary data models to store and manage loyalty points for customers. + +Refer to the [Modules documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md) to learn more. + +### Create Module Directory + +Modules are created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/loyalty`. + +### Create Data Models + +A data model represents a table in the database. You create data models using Medusa's Data Model Language (DML). It simplifies defining a table's columns, relations, and indexes with straightforward methods and configurations. + +Refer to the [Data Models documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#1-create-data-model/index.html.md) to learn more. + +For the Loyalty Module, you need to define a `LoyaltyPoint` data model that represents a customer's loyalty points. So, create the file `src/modules/loyalty/models/loyalty-point.ts` with the following content: + +```ts title="src/modules/loyalty/models/loyalty-point.ts" highlights={dmlHighlights} +import { model } from "@medusajs/framework/utils" + +const LoyaltyPoint = model.define("loyalty_point", { + id: model.id().primaryKey(), + points: model.number().default(0), + customer_id: model.text().unique("IDX_LOYALTY_CUSTOMER_ID"), +}) + +export default LoyaltyPoint +``` + +You define the `LoyaltyPoint` data model using the `model.define` method of the DML. It accepts the data model's table name as a first parameter, and the model's schema object as a second parameter. + +The `LoyaltyPoint` data model has the following properties: + +- `id`: A unique ID for the loyalty points. +- `points`: The number of loyalty points a customer has. +- `customer_id`: The ID of the customer who owns the loyalty points. This property has a unique index to ensure that each customer has only one record in the `loyalty_point` table. + +Learn more about defining data model properties in the [Property Types documentation](https://docs.medusajs.com/docs/learn/fundamentals/data-models/properties/index.html.md). + +### Create Module's Service + +You now have the necessary data model in the Loyalty Module, but you'll need to manage its records. You do this by creating a service in the module. + +A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, allowing you to manage your data models, or connect to a third-party service, which is useful if you're integrating with external services. + +Refer to the [Module Service documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#2-create-service/index.html.md) to learn more. + +To create the Loyalty Module's service, create the file `src/modules/loyalty/service.ts` with the following content: + +```ts title="src/modules/loyalty/service.ts" +import { MedusaError, MedusaService } from "@medusajs/framework/utils" +import LoyaltyPoint from "./models/loyalty-point" +import { InferTypeOf } from "@medusajs/framework/types" + +type LoyaltyPoint = InferTypeOf + +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + // TODO add methods +} + +export default LoyaltyModuleService +``` + +The `LoyaltyModuleService` extends `MedusaService` from the Modules SDK which generates a class with data-management methods for your module's data models. This saves you time on implementing Create, Read, Update, and Delete (CRUD) methods. + +So, the `LoyaltyModuleService` class now has methods like `createLoyaltyPoints` and `retrieveLoyaltyPoint`. + +Find all methods generated by the `MedusaService` in [the Service Factory reference](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/service-factory-reference/index.html.md). + +#### Add Methods to the Service + +Aside from the basic CRUD methods, you need to add methods that handle custom functionalities related to loyalty points. + +First, you need a method that adds loyalty points for a customer. Add the following method to the `LoyaltyModuleService`: + +```ts title="src/modules/loyalty/service.ts" +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + async addPoints(customerId: string, points: number): Promise { + const existingPoints = await this.listLoyaltyPoints({ + customer_id: customerId, + }) + + if (existingPoints.length > 0) { + return await this.updateLoyaltyPoints({ + id: existingPoints[0].id, + points: existingPoints[0].points + points, + }) + } + + return await this.createLoyaltyPoints({ + customer_id: customerId, + points, + }) + } +} +``` + +You add an `addPoints` method that accepts two parameters: the ID of the customer and the points to add. + +In the method, you retrieve the customer's existing loyalty points using the `listLoyaltyPoints` method, which is automatically generated by the `MedusaService`. If the customer has existing points, you update them with the new points using the `updateLoyaltyPoints` method. + +Otherwise, if the customer doesn't have existing loyalty points, you create a new record with the `createLoyaltyPoints` method. + +The next method you'll add deducts points from the customer's loyalty points, which is useful when the customer redeems points. Add the following method to the `LoyaltyModuleService`: + +```ts title="src/modules/loyalty/service.ts" +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + // ... + async deductPoints(customerId: string, points: number): Promise { + const existingPoints = await this.listLoyaltyPoints({ + customer_id: customerId, + }) + + if (existingPoints.length === 0 || existingPoints[0].points < points) { + throw new MedusaError( + MedusaError.Types.NOT_ALLOWED, + "Insufficient loyalty points" + ) + } + + return await this.updateLoyaltyPoints({ + id: existingPoints[0].id, + points: existingPoints[0].points - points, + }) + } +} +``` + +The `deductPoints` method accepts the customer ID and the points to deduct. + +In the method, you retrieve the customer's existing loyalty points using the `listLoyaltyPoints` method. If the customer doesn't have existing points or if the points to deduct are greater than the existing points, you throw an error. + +Otherwise, you update the customer's loyalty points with the new value using the `updateLoyaltyPoints` method, which is automatically generated by `MedusaService`. + +Next, you'll add the method that retrieves the points of a customer. Add the following method to the `LoyaltyModuleService`: + +```ts title="src/modules/loyalty/service.ts" +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + // ... + async getPoints(customerId: string): Promise { + const points = await this.listLoyaltyPoints({ + customer_id: customerId, + }) + + return points[0]?.points || 0 + } +} +``` + +The `getPoints` method accepts the customer ID and retrieves the customer's loyalty points using the `listLoyaltyPoints` method. If the customer has no points, it returns `0`. + +#### Add Method to Map Points to Discount + +Finally, you'll add a method that implements the logic of mapping loyalty points to a discount amount. This is useful when the customer wants to redeem their points during checkout. + +The mapping logic may differ for each use case. For example, you may need to use a third-party service to map the loyalty points discount amount, or use some custom calculation. + +To simplify the logic in this tutorial, you'll use a simple calculation that maps 1 point to 1 currency unit. For example, `100` points = `$100` discount. + +Add the following method to the `LoyaltyModuleService`: + +```ts title="src/modules/loyalty/service.ts" +class LoyaltyModuleService extends MedusaService({ + LoyaltyPoint, +}) { + // ... + async calculatePointsFromAmount(amount: number): Promise { + // Convert amount to points using a standard conversion rate + // For example, $1 = 1 point + // Round down to nearest whole point + const points = Math.floor(amount) + + if (points < 0) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Amount cannot be negative" + ) + } + + return points + } +} +``` + +The `calculatePointsFromAmount` method accepts the amount and converts it to the nearest whole number of points. If the amount is negative, it throws an error. + +You'll use this method later to calculate the amount discounted when a customer redeems their loyalty points. + +### Export Module Definition + +The final piece to a module is its definition, which you export in an `index.ts` file at its root directory. This definition tells Medusa the name of the module and its service. + +So, create the file `src/modules/loyalty/index.ts` with the following content: + +```ts title="src/modules/loyalty/index.ts" +import { Module } from "@medusajs/framework/utils" +import LoyaltyModuleService from "./service" + +export const LOYALTY_MODULE = "loyalty" + +export default Module(LOYALTY_MODULE, { + service: LoyaltyModuleService, +}) +``` + +You use the `Module` function from the Modules SDK to create the module's definition. It accepts two parameters: + +1. The module's name, which is `loyalty`. +2. An object with a required property `service` indicating the module's service. + +You also export the module's name as `LOYALTY_MODULE` so you can reference it later. + +### Add Module to Medusa's Configurations + +Once you finish building the module, add it to Medusa's configurations to start using it. + +In `medusa-config.ts`, add a `modules` property and pass an array with your custom module: + +```ts title="medusa-config.ts" +module.exports = defineConfig({ + // ... + modules: [ + { + resolve: "./src/modules/loyalty", + }, + ], +}) +``` + +Each object in the `modules` array has a `resolve` property, whose value is either a path to the module's directory, or an `npm` package’s name. + +### Generate Migrations + +Since data models represent tables in the database, you define how they're created in the database with migrations. A migration is a TypeScript or JavaScript file that defines database changes made by a module. + +Refer to the [Migrations documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules#5-generate-migrations/index.html.md) to learn more. + +Medusa's CLI tool can generate the migrations for you. To generate a migration for the Loyalty Module, run the following command in your Medusa application's directory: + +```bash +npx medusa db:generate loyalty +``` + +The `db:generate` command of the Medusa CLI accepts the name of the module to generate the migration for. You'll now have a `migrations` directory under `src/modules/loyalty` that holds the generated migration. + +Then, to reflect these migrations on the database, run the following command: + +```bash +npx medusa db:migrate +``` + +The table for the `LoyaltyPoint` data model is now created in the database. + +*** + +## Step 3: Change Loyalty Points Flow + +Now that you have a module that stores and manages loyalty points in the database, you'll start building flows around it that allow customers to earn and redeem points. + +The first flow you'll build will either add points to a customer's loyalty points or deduct them based on a purchased order. If the customer hasn't redeemed points, the points are added to their loyalty points. Otherwise, the points are deducted from their loyalty points. + +To build custom commerce features in Medusa, you create a [workflow](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). A workflow is a series of queries and actions, called steps, that complete a task. You construct a workflow like you construct a function, but it's a special function that allows you to track its executions' progress, define roll-back logic, and configure other advanced features. Then, you execute the workflow from other customizations, such as in an endpoint. + +In this section, you'll build the workflow that adds or deducts loyalty points for an order's customer. Later, you'll execute this workflow when an order is placed. + +Learn more about workflows in the [Workflows documentation](https://docs.medusajs.com/docs/learn/fundamentals/workflows/index.html.md). + +The workflow will have the following steps: + +- [useQueryGraphStep](https://docs.medusajs.com/references/helper-steps/useQueryGraphStep/index.html.md): Retrieve the order's details. +- [validateCustomerExistsStep](#validateCustomerExistsStep): Validate that the customer is registered. +- [getCartLoyaltyPromoStep](#getCartLoyaltyPromoStep): Retrieve the cart's loyalty promotion. + +Medusa provides the `useQueryGraphStep` and `updatePromotionsStep` in its `@medusajs/medusa/core-flows` package. So, you'll only implement the other steps. + +### validateCustomerExistsStep + +In the workflow, you first need to validate that the customer is registered. Only registered customers can earn and redeem loyalty points. + +To do this, create the file `src/workflows/steps/validate-customer-exists.ts` with the following content: + +```ts title="src/workflows/steps/validate-customer-exists.ts" +import { CustomerDTO } from "@medusajs/framework/types" +import { createStep } from "@medusajs/framework/workflows-sdk" +import { MedusaError } from "@medusajs/framework/utils" + +export type ValidateCustomerExistsStepInput = { + customer: CustomerDTO | null | undefined +} + +export const validateCustomerExistsStep = createStep( + "validate-customer-exists", + async ({ customer }: ValidateCustomerExistsStepInput) => { + if (!customer) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Customer not found" + ) + } + + if (!customer.has_account) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Customer must have an account to earn or manage points" + ) + } + } +) +``` + +You create a step with `createStep` from the Workflows SDK. It accepts two parameters: + +1. The step's unique name, which is `validate-customer-exists`. +2. An async function that receives two parameters: + - The step's input, which is in this case an object with the customer's details. + - An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md), which is a registry of Framework and commerce tools that you can access in the step. + +In the step function, you validate that the customer is defined and that it's registered based on its `has_account` property. Otherwise, you throw an error. + +### getCartLoyaltyPromoStep + +Next, you'll need to retrieve the loyalty promotion applied on the cart, if there's any. This is useful to determine whether the customer has redeemed points. + +Before you create a step, you'll create a utility function that the step uses to retrieve the loyalty promotion of a cart. You'll create it as a separate utility function to use it later in other customizations. + +Create the file `src/utils/promo.ts` with the following content: + +```ts title="src/utils/promo.ts" +import { PromotionDTO, CustomerDTO, CartDTO } from "@medusajs/framework/types" + +export type CartData = CartDTO & { + promotions?: PromotionDTO[] + customer?: CustomerDTO + metadata: { + loyalty_promo_id?: string + } +} + +export function getCartLoyaltyPromotion( + cart: CartData +): PromotionDTO | undefined { + if (!cart?.metadata?.loyalty_promo_id) { + return + } + + return cart.promotions?.find( + (promotion) => promotion.id === cart.metadata.loyalty_promo_id + ) +} +``` + +You create a `getCartLoyaltyPromotion` function that accepts the cart's details as an input and returns the loyalty promotion if it exists. You retrieve the loyalty promotion if its ID is stored in the cart's `metadata.loyalty_promo_id` property. + +You can now create the step that uses this utility to retrieve a carts loyalty points promotion. To create the step, create the file `src/workflows/steps/get-cart-loyalty-promo.ts` with the following content: + +```ts title="src/workflows/steps/get-cart-loyalty-promo.ts" +import { createStep, StepResponse } from "@medusajs/framework/workflows-sdk" +import { CartData, getCartLoyaltyPromotion } from "../../utils/promo" +import { MedusaError } from "@medusajs/framework/utils" + +type GetCartLoyaltyPromoStepInput = { + cart: CartData, + throwErrorOn?: "found" | "not-found" +} + +export const getCartLoyaltyPromoStep = createStep( + "get-cart-loyalty-promo", + async ({ cart, throwErrorOn }: GetCartLoyaltyPromoStepInput) => { + const loyaltyPromo = getCartLoyaltyPromotion(cart) + + if (throwErrorOn === "found" && loyaltyPromo) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "Loyalty promotion already applied to cart" + ) + } else if (throwErrorOn === "not-found" && !loyaltyPromo) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + "No loyalty promotion found on cart" + ) + } + + return new StepResponse(loyaltyPromo) + } +) +``` + +You create a step that accepts an object having the following properties: + +- `cart`: The cart's details. +- `throwErrorOn`: An optional property that indicates whether to throw an error if the loyalty promotion is found or not found. + +The `throwErrorOn` property is useful to make the step reusable in different scenarios, allowing you to use it in later workflows. + +In the step, you call the `getCartLoyaltyPromotion` utility to retrieve the loyalty promotion. If the `throwErrorOn` property is set to `found` and the loyalty promotion is found, you throw an error. + +Otherwise, if the `throwErrorOn` property is set to `not-found` and the loyalty promotion is not found, you throw an error. + +To return data from a step, you return an instance of `StepResponse` from the Workflows SDK. It accepts as a parameter the data to return, which is the loyalty promotion in this case. + +### deductPurchasePointsStep + +If the order's cart has a loyalty promotion, you need to deduct points from the customer's loyalty points. To do this, create the file `src/workflows/steps/deduct-purchase-points.ts` with the following content: + +```ts title="src/workflows/steps/deduct-purchase-points.ts" highlights={deductStepHighlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import { LOYALTY_MODULE } from "../../modules/loyalty" +import LoyaltyModuleService from "../../modules/loyalty/service" + +type DeductPurchasePointsInput = { + customer_id: string + amount: number +} + +export const deductPurchasePointsStep = createStep( + "deduct-purchase-points", + async ({ + customer_id, amount, + }: DeductPurchasePointsInput, { container }) => { + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + const pointsToDeduct = await loyaltyModuleService.calculatePointsFromAmount( + amount + ) + + const result = await loyaltyModuleService.deductPoints( + customer_id, + pointsToDeduct + ) + + return new StepResponse(result, { + customer_id, + points: pointsToDeduct, + }) + }, + async (data, { container }) => { + if (!data) { + return + } + + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + // Restore points in case of failure + await loyaltyModuleService.addPoints( + data.customer_id, + data.points + ) + } +) +``` + +You create a step that accepts an object having the following properties: + +- `customer_id`: The ID of the customer to deduct points from. +- `amount`: The promotion's amount, which will be used to calculate the points to deduct. + +In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you use the `calculatePointsFromAmount` method to calculate the points to deduct from the promotion's amount. + +After that, you call the `deductPoints` method to deduct the points from the customer's loyalty points. + +Finally, you return a `StepResponse` with the result of the `deductPoints`. + +#### Compensation Function + +This step has a compensation function, which is passed as a third parameter to the `createStep` function. + +The compensation function undoes the actions performed in a step. Then, if an error occurs during the workflow's execution, the compensation functions of executed steps are called to roll back the changes. This mechanism ensures data consistency in your application, especially as you integrate external systems. + +The compensation function accepts two parameters: + +1. Data passed from the step function to the compensation function. The data is passed as a second parameter of the returned `StepResponse` instance. +2. An object that has properties including the [Medusa container](https://docs.medusajs.com/docs/learn/fundamentals/medusa-container/index.html.md). + +In the compensation function, you resolve the Loyalty Module's service from the Medusa container. Then, you call the `addPoints` method to restore the points deducted from the customer's loyalty points if an error occurs. + +### addPurchaseAsPointsStep + +The last step you'll create adds points to the customer's loyalty points. You'll use this step if the customer didn't redeem points during checkout. + +To create the step, create the file `src/workflows/steps/add-purchase-as-points.ts` with the following content: + +```ts title="src/workflows/steps/add-purchase-as-points.ts" highlights={addPointsHighlights} collapsibleLines="1-7" expandButtonLabel="Show Imports" +import { + createStep, + StepResponse, +} from "@medusajs/framework/workflows-sdk" +import { LOYALTY_MODULE } from "../../modules/loyalty" +import LoyaltyModuleService from "../../modules/loyalty/service" + +type StepInput = { + customer_id: string + amount: number +} + +export const addPurchaseAsPointsStep = createStep( + "add-purchase-as-points", + async (input: StepInput, { container }) => { + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + const pointsToAdd = await loyaltyModuleService.calculatePointsFromAmount( + input.amount + ) + + const result = await loyaltyModuleService.addPoints( + input.customer_id, + pointsToAdd + ) + + return new StepResponse(result, { + customer_id: input.customer_id, + points: pointsToAdd, + }) + }, + async (data, { container }) => { + if (!data) { + return + } + + const loyaltyModuleService: LoyaltyModuleService = container.resolve( + LOYALTY_MODULE + ) + + await loyaltyModuleService.deductPoints( + data.customer_id, + data.points + ) + } +) +``` + +You create a step that accepts an object having the following properties: + +- `customer_id`: The ID of the customer to add points to. +- `amount`: The order's amount, which will be used to calculate the points to add. + +In the step, you resolve the Loyalty Module's service from the Medusa container. Then, you use the `calculatePointsFromAmount` method to calculate the points to add from the order's amount. + +After that, you call the `addPoints` method to add the points to the customer's loyalty points. + +Finally, you return a `StepResponse` with the result of the `addPoints`. + +You also pass to the compensation function the customer's ID and the points added. In the compensation function, you deduct the points if an error occurs. + +### Add Utility Functions + +Before you create the workflow, you need a utility function that checks whether an order's cart has a loyalty promotion. This is useful to determine whether the customer redeemed points during checkout, allowing you to decide which steps to execute. + +To add the utility function, add the following to `src/utils/promo.ts`: + +```ts title="src/utils/promo.ts" +import { OrderDTO } from "@medusajs/framework/types" + +export type OrderData = OrderDTO & { + promotion?: PromotionDTO[] + customer?: CustomerDTO + cart?: CartData +} + +export const CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE = "customer_id" + +export function orderHasLoyaltyPromotion(order: OrderData): boolean { + const loyaltyPromotion = getCartLoyaltyPromotion( + order.cart as unknown as CartData + ) + + return loyaltyPromotion?.rules?.some((rule) => { + return rule?.attribute === CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE && ( + rule?.values?.some((value) => value.value === order.customer?.id) || false + ) + }) || false +} +``` + +You first define an `OrderData` type that extends the `OrderDTO` type. This type has the order's details, including the cart, customer, and promotions details. + +Then, you define a constant `CUSTOMER_ID_PROMOTION_RULE_ATTRIBUTE` that represents the attribute used in the promotion rule to check whether the customer ID is valid. + +Finally, you create the `orderHasLoyaltyPromotion` function that accepts an order's details and checks whether it has a loyalty promotion. It returns `true` if: + +- The order's cart has a loyalty promotion. You use the `getCartLoyaltyPromotion` utility to try to retrieve the loyalty promotion. +- The promotion's rules include the `customer_id` attribute and its value matches the order's customer ID. + - When you create the promotion for the cart later, you'll see how to set this rule. + +You'll use this utility in the workflow next. + +### Create the Workflow + +Now that you have all the steps, you can create the workflow that uses them. + +To create the workflow, create the file `src/workflows/handle-order-points.ts` with the following content: + +```ts title="src/workflows/handle-order-points.ts" highlights={handleOrderPointsHighlights} collapsibleLines="1-9" expandButtonLabel="Show Imports" +import { createWorkflow, when } from "@medusajs/framework/workflows-sdk" +import { updatePromotionsStep, useQueryGraphStep } from "@medusajs/medusa/core-flows" +import { validateCustomerExistsStep, ValidateCustomerExistsStepInput } from "./steps/validate-customer-exists" +import { deductPurchasePointsStep } from "./steps/deduct-purchase-points" +import { addPurchaseAsPointsStep } from "./steps/add-purchase-as-points" +import { OrderData, CartData } from "../utils/promo" +import { orderHasLoyaltyPromotion } from "../utils/promo" +import { getCartLoyaltyPromoStep } from "./steps/get-cart-loyalty-promo" + +type WorkflowInput = { + order_id: string +} + +export const handleOrderPointsWorkflow = createWorkflow( + "handle-order-points", + ({ order_id }: WorkflowInput) => { + // @ts-ignore + const { data: orders } = useQueryGraphStep({ + entity: "order", + fields: [ + "id", + "customer.*", + "total", + "cart.*", + "cart.promotions.*", + "cart.promotions.rules.*", + "cart.promotions.rules.values.*", + "cart.promotions.application_method.*", + ], + filters: { + id: order_id, + }, + options: { + throwIfKeyNotFound: true, + }, + }) + + validateCustomerExistsStep({ + customer: orders[0].customer, + } as ValidateCustomerExistsStepInput) + + const loyaltyPointsPromotion = getCartLoyaltyPromoStep({ + cart: orders[0].cart as unknown as CartData, + }) + + when(orders, (orders) => + orderHasLoyaltyPromotion(orders[0] as unknown as OrderData) && + loyaltyPointsPromotion !== undefined + ) + .then(() => { + deductPurchasePointsStep({ + customer_id: orders[0].customer!.id, + amount: loyaltyPointsPromotion.application_method!.value as number, + }) + + updatePromotionsStep([ + { + id: loyaltyPointsPromotion.id, + status: "inactive", + }, + ]) + }) + + + when( + orders, + (order) => !orderHasLoyaltyPromotion(order[0] as unknown as OrderData) + ) + .then(() => { + addPurchaseAsPointsStep({ + customer_id: orders[0].customer!.id, + amount: orders[0].total, + }) + }) + } +) +``` + +You create a workflow using `createWorkflow` from the Workflows SDK. It accepts the workflow's unique name as a first parameter. + +It accepts as a second parameter a constructor function, which is the workflow's implementation. The function can accept input, which in this case is an object with the order's ID. + +In the workflow's constructor function, you: + +- Use `useQueryGraphStep` to retrieve the order's details. You pass the order's ID as a filter to retrieve the order. + - This step uses [Query](https://docs.medusajs.com/docs/learn/fundamentals/module-links/query/index.html.md), which is a tool that retrieves data across modules. +- Validate that the customer is registered using the `validateCustomerExistsStep`. +- Retrieve the cart's loyalty promotion using the `getCartLoyaltyPromoStep`. +- Use `when` to check whether the order's cart has a loyalty promotion. + - Since you can't perform data manipulation in a workflow's constructor function, `when` allows you to perform steps if a condition is satisfied. + - You pass as a first parameter the object to perform the condition on, which is the order in this case. In the second parameter, you pass a function that returns a boolean value, indicating whether the condition is satisfied. + - To specify the steps to perform if a condition is satisfied, you chain a `then` method to the `when` method. You can perform any step within the `then` method. + - In this case, if the order's cart has a loyalty promotion, you call the `deductPurchasePointsStep` to deduct points from the customer's loyalty points. You also call the `updatePromotionsStep` to deactivate the cart's loyalty promotion. +- You use another `when` to check whether the order's cart doesn't have a loyalty promotion. + - If the condition is satisfied, you call the `addPurchaseAsPointsStep` to add points to the customer's loyalty points. + +You'll use this workflow next when an order is placed. + +To learn more about the constraints on a workflow's constructor function, refer to the [Workflow Constraints](https://docs.medusajs.com/docs/learn/fundamentals/workflows/constructor-constraints/index.html.md) documentation. Refer to the [When-Then](https://docs.medusajs.com/docs/learn/fundamentals/workflows/conditions/index.html.md) documentation to learn more about the `when` method and how to use it in a workflow. + +*** + +## Step 4: Handle Order Placed Event + +Now that you have the workflow that handles adding or deducting loyalty points for an order, you need to execute it when an order is placed. + +Medusa has an event system that allows you to listen to events emitted by the Medusa server using a [subscriber](https://docs.medusajs.com/docs//learn/fundamentals/events-and-subscribers/index.html.md). A subscriber is an asynchronous function that's executed when its associated event is emitted. In a subscriber, you can execute a workflow that performs actions in result of the event. + +In this step, you'll create a subscriber that listens to the `order.placed` event and executes the `handleOrderPointsWorkflow` workflow. + +Refer to the [Events and Subscribers](https://docs.medusajs.com/docs/learn/fundamentals/events-and-subscribers/index.html.md) documentation to learn more. + +Subscribers are created in a TypeScript or JavaScript file under the `src/subscribers` directory. So, to create a subscriber, create the fle `src/subscribers/order-placed.ts` with the following content: + +```ts title="src/subscribers/order-placed.ts" +import type { + SubscriberArgs, + SubscriberConfig, +} from "@medusajs/framework" +import { handleOrderPointsWorkflow } from "../workflows/handle-order-points" + +export default async function orderPlacedHandler({ + event: { data }, + container, +}: SubscriberArgs<{ id: string }>) { + await handleOrderPointsWorkflow(container).run({ + input: { + order_id: data.id, + }, + }) +} + +export const config: SubscriberConfig = { + event: "order.placed", +} +``` + +The subscriber file must export: + +- An asynchronous subscriber function that's executed whenever the associated event, which is `order.placed` is triggered. +- A configuration object with an event property whose value is the event the subscriber is listening to. You can also pass an array of event names to listen to multiple events in the same subscriber. + +The subscriber function accepts an object with the following properties: + +- `event`: An object with the event's data payload. For example, the `order.placed` event has the order's ID in its data payload. +- `container`: The Medusa container, which you can use to resolve services and tools. + +In the subscriber function, you execute the `handleOrderPointsWorkflow` by invoking it, passing it the Medusa container, then using its `run` method, passing it the workflow's input. + +Whenever an order is placed now, the subscriber will be executed, which in turn will execute the workflow that handles the loyalty points flow. + +### Test it Out + +To test out the loyalty points flow, you'll use the [Next.js Starter Storefront](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/nextjs-starter/index.html.md) that you installed in the first step. As mentioned in that step, the storefront will be installed in a separate directory from the Medusa application, and its name is `{project-name}-storefront`, where `{project-name}` is the name of your Medusa application's directory. + +So, run the following command in the Medusa application's directory to start the Medusa server: + +```bash title="Medusa Application" +npm run dev +``` + +Then, run the following command in the Next.js Starter Storefront's directory to start the Next.js server: + +```bash title="Next.js Starter Storefront" +npm run dev +``` + +The Next.js Starter Storefront will be running on `http://localhost:8000`, and the Medusa server will be running on `http://localhost:9000`. + +Open the Next.js Starter Storefront in your browser and create a new account by going to Account at the top right. + +Once you're logged in, add an item to the cart and go through the checkout flow. + +After you place the order, you'll see the following message in your Medusa application's terminal: + +```bash +info: Processing order.placed which has 1 subscribers +``` + +This message indicates that the `order.placed` event was emitted, and that your subscriber was executed. + +Since you didn't redeem any points during checkout, loyalty points will be added to your account. You'll implement an API route that allows you to retrieve the loyalty points in the next step. + +*** + +## Step 5: Retrieve Loyalty Points API Route + +Next, you want to allow customers to view their loyalty points. You can show them on their profile page, or during checkout. + +To expose a feature to clients, you create an [API route](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). An API Route is an endpoint that exposes commerce features to external applications and clients, such as storefronts. + +You'll create an API route at the path `/store/customers/me/loyalty-points` that returns the loyalty points of the authenticated customer. + +Learn more about API routes in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/api-routes/index.html.md). + +An API route is created in a `route.ts` file under a sub-directory of the `src/api` directory. The path of the API route is the file's path relative to `src/api`. + +So, to create an API route at the path `/store/customers/me/loyalty-points`, create the file `src/api/store/customers/me/loyalty-points/route.ts` with the following content: + +```ts title="src/api/store/customers/me/loyalty-points/route.ts" + +import { + AuthenticatedMedusaRequest, + MedusaResponse, +} from "@medusajs/framework/http" +import { LOYALTY_MODULE } from "../../../../../modules/loyalty" +import LoyaltyModuleService from "../../../../../modules/loyalty/service" + +export async function GET( + req: AuthenticatedMedusaRequest, + res: MedusaResponse +) { + const loyaltyModuleService: LoyaltyModuleService = req.scope.resolve( + LOYALTY_MODULE + ) + + const points = await loyaltyModuleService.getPoints( + req.auth_context.actor_id + ) + + res.json({ + points, + }) +} +``` + +Since you export a `GET` route handler function, you're exposing a `GET` endpoint at `/store/customers/me/loyalty-points`. The route handler function accepts two parameters: + +1. A request object with details and context on the request, such as body parameters or authenticated customer details. +2. A response object to manipulate and send the response. + +In the route handler, you resolve the Loyalty Module's service from the Medusa container (which is available at `req.scope`). + +Then, you call the service's `getPoints` method to retrieve the authenticated customer's loyalty points. Note that routes starting with `/store/customers/me` are only accessible by authenticated customers. You can access the authenticated customer ID from the request's context, which is available at `req.auth_context.actor_id`. + +Finally, you return the loyalty points in the response. + +You'll test out this route as you customize the Next.js Starter Storefront next. + +*** + +## Step 6: Show Loyalty Points During Checkout + +Now that you have the API route to retrieve the loyalty points, you can show them during checkout. + +In this step, you'll customize the Next.js Starter Storefront to show the loyalty points in the checkout page. + +First, you'll add a server action function that retrieves the loyalty points from the route you created earlier. In `src/lib/data/customer.ts`, add the following function: + +```ts title="src/lib/data/customer.ts" badgeLabel="Storefront" badgeColor="blue" +export const getLoyaltyPoints = async () => { + const headers = { + ...(await getAuthHeaders()), + } + + return sdk.client.fetch<{ points: number }>( + `/store/customers/me/loyalty-points`, + { + method: "GET", + headers, + } + ) + .then(({ points }) => points) + .catch(() => null) +} +``` + +You add a `getLoyaltyPoints` function that retrieves the authenticated customer's loyalty points from the API route you created earlier. You pass the authentication headers using the `getAuthHeaders` function, which is a utility function defined in the Next.js Starter Storefront. + +If the customer isn't authenticated, the request will fail. So, you catch the error and return `null` in that case. + +Next, you'll create a component that shows the loyalty points in the checkout page. Create the file `src/modules/checkout/components/loyalty-points/index.tsx` with the following content: + +```tsx title="src/modules/checkout/components/loyalty-points/index.tsx" badgeLabel="Storefront" badgeColor="blue" highlights={loyaltyPointsHighlights} +"use client" + +import { HttpTypes } from "@medusajs/types" +import { useEffect, useMemo, useState } from "react" +import { getLoyaltyPoints } from "../../../../lib/data/customer" +import { Button, Heading } from "@medusajs/ui" +import Link from "next/link" + +type LoyaltyPointsProps = { + cart: HttpTypes.StoreCart & { + promotions: HttpTypes.StorePromotion[] + } +} + +const LoyaltyPoints = ({ cart }: LoyaltyPointsProps) => { + const isLoyaltyPointsPromoApplied = useMemo(() => { + return cart.promotions.find( + (promo) => promo.id === cart.metadata?.loyalty_promo_id + ) !== undefined + }, [cart]) + const [loyaltyPoints, setLoyaltyPoints] = useState< + number | null + >(null) + + useEffect(() => { + getLoyaltyPoints() + .then((points) => { + console.log(points) + setLoyaltyPoints(points) + }) + }, []) + + const handleTogglePromotion = async ( + e: React.MouseEvent + ) => { + e.preventDefault() + // TODO apply or remove loyalty promotion + } + + return ( + <> +
+
+ + Loyalty Points + + {loyaltyPoints === null && ( + + Sign up to get and use loyalty points + + )} + {loyaltyPoints !== null && ( +
+ + + You have {loyaltyPoints} loyalty points + +
+ )} +
+ + ) +} + +export default LoyaltyPoints +``` + +You create a `LoyaltyPoints` component that accepts the cart's details as a prop. In the component, you: + +- Create a `isLoyaltyPointsPromoApplied` memoized value that checks whether the cart has a loyalty promotion applied. You use the `cart.metadata.loyalty_promo_id` property to check this. +- Create a `loyaltyPoints` state to store the customer's loyalty points. +- Call the `getLoyaltyPoints` function in a `useEffect` hook to retrieve the loyalty points from the API route you created earlier. You set the `loyaltyPoints` state with the retrieved points. +- Define `handleTogglePromotion` that, when clicked, would either apply or remove the promotion. You'll implement these functionalities later. +- Render the loyalty points in the component. If the customer isn't authenticated, you show a link to the account page to sign up. Otherwise, you show the loyalty points and a button to apply or remove the promotion. + +Next, you'll show this component at the end of the checkout's summary component. So, import the component in `src/modules/checkout/templates/checkout-summary/index.tsx`: + +```tsx title="src/modules/checkout/templates/checkout-summary/index.tsx" badgeLabel="Storefront" badgeColor="blue" +import LoyaltyPoints from "../../components/loyalty-points" +``` + +Then, in the return statement of the `CheckoutSummary` component, add the following after the `div` wrapping the `DiscountCode`: + +```tsx title="src/modules/checkout/templates/checkout-summary/index.tsx" badgeLabel="Storefront" badgeColor="blue" + +``` + +This will show the loyalty points component at the end of the checkout summary. + +### Test it Out + +To test out the customizations to the checkout flow, make sure both the Medusa application and Next.js Starter Storefront are running. + +Then, as an authenticated customer, add an item to cart and proceed to checkout. You'll find a new "Loyalty Points" section at the end of the checkout summary. + +![Loyalty Points Section at the end of the summary section at the right](https://res.cloudinary.com/dza7lstvk/image/upload/v1744195223/Medusa%20Resources/Screenshot_2025-04-09_at_1.39.34_PM_l5oltc.png) + +If you made a purchase before, you can see your loyalty points. You'll also see the "Apply Loyalty Points" button, which doesn't yet do anything. You'll add the functionality next. + +*** + +## Step 7: Apply Loyalty Points to Cart + +The next feature you'll implement allows the customer to apply their loyalty points during checkout. To implement the feature, you need: + +- A workflow that implements the steps of the apply loyalty points flow. +- An API route that exposes the workflow's functionality to clients.

In this step, you'll create a ShipStation Module Provider that implements all functionalities required for fulfillment. In later steps, you'll add into Medusa shipping options for ShipStation, and allow customers to choose it during checkout. + +Learn more about modules in [this documentation](https://docs.medusajs.com/docs/learn/fundamentals/modules/index.html.md). + +### Create Module Directory + +A module is created under the `src/modules` directory of your Medusa application. So, create the directory `src/modules/shipstation`. + +![The directory structure of the Medusa application after adding the module's directory](https://res.cloudinary.com/dza7lstvk/image/upload/v1734338950/Medusa%20Resources/shipstation-dir-overview-1_dlsrbv.jpg) + +### Create Service + +You define a module's functionalities in a service. A service is a TypeScript or JavaScript class that the module exports. In the service's methods, you can connect to the database, which is useful if your module defines tables in the database, or connect to a third-party service. + +In this section, you'll create the ShipStation Module Provider's service and the methods necessary to handle fulfillment. + +Start by creating the file `src/modules/shipstation/service.ts` with the following content: + +![The directory structure of the Medusa application after adding the service](https://res.cloudinary.com/dza7lstvk/image/upload/v1734339042/Medusa%20Resources/shipstation-dir-overview-2_cmgvcj.jpg) + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights1} +import { AbstractFulfillmentProviderService } from "@medusajs/framework/utils" + +export type ShipStationOptions = { + api_key: string +} + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + static identifier = "shipstation" + protected options_: ShipStationOptions + + constructor({}, options: ShipStationOptions) { + super() + + this.options_ = options + } + + // TODO add methods +} + +export default ShipStationProviderService +``` + +A Fulfillment Module Provider service must extend the `AbstractFulfillmentProviderService` class. You'll implement the abstract methods of this class in the upcoming sections. + +The service must have an `identifier` static property, which is a unique identifier for the provider. You set the identifier to `shipstation`. + +A module can receive options that are set when you later add the module to Medusa's configurations. These options allow you to safely store secret values outside of your code. + +The ShipStation module requires an `api_key` option, indicating your ShipStation's API key. You receive the options as a second parameter of the service's constructor. + +### Create Client + +To send requests to ShipStation, you'll create a client class that provides the methods to send requests. You'll then use that class in your service. + +Create the file `src/modules/shipstation/client.ts` with the following content: + +![The directory structure of the Medusa application after adding the client file](https://res.cloudinary.com/dza7lstvk/image/upload/v1734339519/Medusa%20Resources/shipstation-dir-overview-3_b8im2d.jpg) + +```ts title="src/modules/shipstation/client.ts" highlights={clientHighlights1} +import { ShipStationOptions } from "./service" +import { MedusaError } from "@medusajs/framework/utils" + +export class ShipStationClient { + options: ShipStationOptions + + constructor(options) { + this.options = options + } + + private async sendRequest(url: string, data?: RequestInit): Promise { + return fetch(`https://api.shipstation.com/v2${url}`, { + ...data, + headers: { + ...data?.headers, + "api-key": this.options.api_key, + "Content-Type": "application/json", + }, + }).then((resp) => { + const contentType = resp.headers.get("content-type") + if (!contentType?.includes("application/json")) { + return resp.text() + } + + return resp.json() + }) + .then((resp) => { + if (typeof resp !== "string" && resp.errors?.length) { + throw new MedusaError( + MedusaError.Types.INVALID_DATA, + `An error occured while sending a request to ShipStation: ${ + resp.errors.map((error) => error.message) + }` + ) + } + + return resp + }) + } +} +``` + +The `ShipStationClient` class accepts the ShipStation options in its constructor and sets those options in the `options` property. + +You also add a private `sendRequest` method that accepts a path to send a request to and the request's configurations. In the method, you send a request using the Fetch API, passing the API key from the options in the request header. You also parse the response body based on its content type, and check if there are any errors to be thrown before returning the parsed response. + +You'll add more methods to send requests in the upcoming steps. + +To use the client in `ShipStationProviderService`, add it as a class property and initialize it in the constructor: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights2} +// imports... +import { ShipStationClient } from "./client" + +// ... + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // properties... + protected client: ShipStationClient + + constructor({}, options: ShipStationOptions) { + // ... + this.client = new ShipStationClient(options) + } +} +``` + +You import `ShipStationClient` and add a new `client` property in `ShipStationProviderService`. In the class's constructor, you set the `client` property by initializing `ShipStationProviderService`, passing it the module's options. + +You'll use the `client` property when implementing the service's methods. + +### Implement Service Methods + +In this section, you'll go back to the `ShipStationProviderService` method to implement the abstract methods of `AbstractFulfillmentProviderService`. + +Refer to [this guide](https://docs.medusajs.com/references/fulfillment/provider/index.html.md) for a full reference of all methods, their parameters and return types. + +#### getFulfillmentOptions + +The `getFulfillmentOptions` method returns the options that this fulfillment provider supports. When admin users add shipping options later in the Medusa Admin, they'll select one of these options. + +Learn more about shipping options in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/fulfillment/shipping-option/index.html.md). + +ShipStation requires that a shipment must be associated with a carrier and one of its services. So, in this method, you'll retrieve the list of carriers from ShipStation and return them as fulfillment options. Shipping options created from these fulfillment options will always have access to the option's carrier and service. + +Before you start implementing methods, you'll add the expected carrier types returned by ShipStation. Create the file `src/modules/shipstation/types.ts` with the following content: + +![The directory structure of the Medusa application after adding the types file](https://res.cloudinary.com/dza7lstvk/image/upload/v1734340402/Medusa%20Resources/shipstation-dir-overview-4_fwsle0.jpg) + +```ts title="src/modules/shipstation/types.ts" +export type Carrier = { + carrier_id: string + disabled_by_billing_plan: boolean + friendly_name: string + services: { + service_code: string + name: string + }[] + packages: { + package_code: string + }[] + [k: string]: unknown +} + +export type CarriersResponse = { + carriers: Carrier[] +} +``` + +You define a `Carrier` type that holds a carrier's details, and a `CarriersResponse` type, which is the response returned by ShipStation. + +A carrier has more fields that you can use. Refer to [ShipStation's documentation](https://docs.shipstation.com/openapi/carriers/list_carriers#carriers/list_carriers/t=response\&c=200\&path=carriers) for all carrier fields. + +Next, you'll add in `ShipStationClient` the method to retrieve the carriers from ShipStation. So, add to the class defined in `src/modules/shipstation/client.ts` a new method: + +```ts title="src/modules/shipstation/client.ts" highlights={clientHighlights2} +// other imports... +import { + CarriersResponse, +} from "./types" + +export class ShipStationClient { + // ... + async getCarriers(): Promise { + return await this.sendRequest("/carriers") + } +} +``` + +You added a new `getCarriers` method that uses the `sendRequest` method to send a request to the [ShipStation's List Carriers endpoint](https://docs.shipstation.com/openapi/carriers/list_carriers). The method returns `CarriersResponse` that you defined earlier. + +Finally, add the `getFulfillmentOptions` method to `ShipStationProviderService`: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights3} +// other imports... +import { + FulfillmentOption, +} from "@medusajs/framework/types" + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async getFulfillmentOptions(): Promise { + const { carriers } = await this.client.getCarriers() + const fulfillmentOptions: FulfillmentOption[] = [] + + carriers + .filter((carrier) => !carrier.disabled_by_billing_plan) + .forEach((carrier) => { + carrier.services.forEach((service) => { + fulfillmentOptions.push({ + id: `${carrier.carrier_id}__${service.service_code}`, + name: service.name, + carrier_id: carrier.carrier_id, + carrier_service_code: service.service_code, + }) + }) + }) + + return fulfillmentOptions + } +} +``` + +In the `getFulfillmentOptions` method, you retrieve the carriers from ShipStation. You then filter out the carriers disabled by your ShipStation billing plan, and loop over the remaining carriers and their services. + +You return an array of fulfillment-option objects, where each object represents a carrier and service pairing. Each object has the following properties: + +- an `id` property, which you set to a combination of the carrier ID and the service code. +- a `name` property, which you set to the service's `name`. The admin user will see this name when they create a shipping option for the ShipStation provider. +- You can pass other data, such as `carrier_id` and `carrier_service_code`, and Medusa will store the fulfillment option in the `data` property of shipping options created later. + +Learn more about the shipping option's `data` property in [this guide](https://docs.medusajs.com/Users/shahednasser/medusa/www/apps/resources/app/commerce-modules/fulfillment/shipping-option/index.html.md). + +You'll see this method in action later when you create a shipping option. + +#### canCalculate + +When an admin user creates a shipping option for your provider, they can choose whether the price is flat rate or calculated during checkout. + +If the user chooses calculated, Medusa validates that your fulfillment provider supports calculated prices using the `canCalculate` method of your provider's service. + +This method accepts the shipping option's `data` field, which will hold the data of an option returned by `getFulfillmentOptions`. It returns a boolean value indicating whether the shipping option can have a calculated price. + +Add the method to `ShipStationProviderService` in `src/modules/shipstation/service.ts`: + +```ts title="src/modules/shipstation/service.ts" +// other imports... +import { + // ... + CreateShippingOptionDTO, +} from "@medusajs/framework/types" + +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async canCalculate(data: CreateShippingOptionDTO): Promise { + return true + } +} +``` + +Since all shipping option prices can be calculated with ShipStation based on the chosen carrier and service zone, you always return `true` in this method. + +You'll implement the calculation mechanism in a later method. + +#### calculatePrice + +When the customer views available shipping options during checkout, the Medusa application requests the calculated price from your fulfillment provider using its `calculatePrice` method. + +To retrieve shipping prices with ShipStation, you create a shipment first then get its rates. So, in the `calculatePrice` method, you'll either: + +- Send a request to [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates) that creates a shipment and returns its prices; +- Or, if a shipment was already created before, you'll retrieve its prices using [ShipStation's get shipment rates endpoint](https://docs.shipstation.com/openapi/shipments/list_shipment_rates). + +First, add the following types to `src/modules/shipstation/types.ts`: + +```ts title="src/modules/shipstation/types.ts" highlights={typesHighlights1} +export type ShipStationAddress = { + name: string + phone: string + email?: string | null + company_name?: string | null + address_line1: string + address_line2?: string | null + address_line3?: string | null + city_locality: string + state_province: string + postal_code: string + country_code: string + address_residential_indicator: "unknown" | "yes" | "no" + instructions?: string | null + geolocation?: { + type?: string + value?: string + }[] +} + +export type Rate = { + rate_id: string + shipping_amount: { + currency: string + amount: number + } + insurance_amount: { + currency: string + amount: number + } + confirmation_amount: { + currency: string + amount: number + } + other_amount: { + currency: string + amount: number + } + tax_amount: { + currency: string + amount: number + } +} + +export type RateResponse = { + rates: Rate[] +} + +export type GetShippingRatesRequest = { + shipment_id?: string + shipment?: Omit + rate_options: { + carrier_ids: string[] + service_codes: string[] + preferred_currency: string + } +} + +export type GetShippingRatesResponse = { + shipment_id: string + carrier_id?: string + service_code?: string + external_order_id?: string + rate_response: RateResponse +} + +export type Shipment = { + shipment_id: string + carrier_id: string + service_code: string + ship_to: ShipStationAddress + return_to?: ShipStationAddress + is_return?: boolean + ship_from: ShipStationAddress + items?: [ + { + name?: string + quantity?: number + sku?: string + } + ] + warehouse_id?: string + shipment_status: "pending" | "processing" | "label_purchased" | "cancelled" + [k: string]: unknown +} + +``` + +You add the following types: + +- `ShipStationAddress`: an address to ship from or to. +- `Rate`: a price rate for a specified carrier and service zone. +- `RateResponse`: The response when retrieving rates. +- `GetShippingRatesRequest`: The request body data for [ShipStation's get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates).

It may have a `tax_amount` property, which is the amount for applied taxes. + +Learn more about these fields in [ShipStation's documentation](https://docs.shipstation.com/rate-shopping#about-the-response). + +The method returns an object having the following properties: + +- `calculated_amount`: The shipping method's price calculated by adding the four rate properties with the tax property, if available. +- `is_calculated_price_tax_inclusive`: Whether the price includes taxes, which is inferred from whether the `tax_amount` property is set in the rate. + +Customers will now see the calculated price of a ShipStation shipping option during checkout. + +#### validateFulfillmentData + +When a customer chooses a shipping option during checkout, Medusa creates a shipping method from that option. A shipping method has a `data` property to store data relevant for later processing of the method and its fulfillments. + +So, in the `validateFulfillmentData` method of your provider, you'll create a shipment in ShipStation if it wasn't already created using their [get shipping rates endpoint](https://docs.shipstation.com/openapi/rates/calculate_rates), and store the ID of that shipment in the created shipping method's `data` property. + +Add the `validateFulfillmentData` method to `ShipStationProviderService`: + +```ts title="src/modules/shipstation/service.ts" highlights={serviceHighlights4} +class ShipStationProviderService extends AbstractFulfillmentProviderService { + // ... + async validateFulfillmentData( + optionData: Record, + data: Record, + context: Record + ): Promise { + let { shipment_id } = data as { + shipment_id?: string + } + + if (!shipment_id) { + const { carrier_id, carrier_service_code } = optionData as { + carrier_id: string + carrier_service_code: string + } + const shipment = await this.createShipment({ + carrier_id, + carrier_service_code, + from_address: { + // @ts-ignore + name: context.from_location?.name, + // @ts-ignore + address: context.from_location?.address, + }, + // @ts-ignore + to_address: context.shipping_address, + // @ts-ignore + items: context.items || [], + // @ts-ignore + currency_code: context.currency_code, + }) + shipment_id = shipment.shipment_id + } + + return { + ...data, + shipment_id, + } + } +} +``` + +The `validateFulfillmentData` method accepts the following parameters: + +1. The `data` property of the chosen shipping option during checkout. It will hold the carrier ID and its service code. +2. The `data` property of the shipping method to be created. This can hold custom data sent in the [Add Shipping Method API route](https://docs.medusajs.com/api/store#carts_postcartsidshippingmethods). +3. An object of the checkout's context, including the cart's items, the location associated with the shipping option, and more. + +In the method, you try to retrieve the shipment ID from the shipping method's `data` parameter if it was already created. If not, you create the shipment in ShipStation using the `createShipment` method. + +Finally, you return the object to be stored in the shipping method's `data` property. You include in it the ID of the shipment in ShipStation. + +#### createFulfillment + +After the customer places the order, the admin user can manage its fulfillments. When the admin user creates a fulfillment for the order, Medusa uses the `createFulfillment` method of the associated provider to handle any processing in the third-party provider. + +This method supports creating split fulfillments, meaning you can partially fulfill and order's items. So, you'll create a new shipment, then purchase a label for that shipment. You'll use the existing shipment to retrieve details like the address to ship from and to. + +First, add a new type to `src/modules/shipstation/types.ts`: + +```ts title="src/modules/shipstation/types.ts" +export type Label = { + label_id: string + status: "processing" | "completed" | "error" | "voided" + shipment_id: string + ship_date: Date + shipment_cost: { + currency: string + amount: number + } + insurance_cost: { + currency: string + amount: number + } + confirmation_amount: { + currency: string + amount: number + } + tracking_number: string + is_return_label: boolean + carrier_id: string + service_code: string + trackable: string + tracking_status: "unknown" | "in_transit" | "error" | "delivered" + label_download: { + href: string + pdf: string + png: string + zpl: string + } +} +``` + +You add the `Label` type for the details in a label object. You can find more properties in [ShipStation's documentation](https://docs.shipstation.com/openapi/labels/create_label#labels/create_label/response\&c=200/body). + +Then, add the following methods to the `ShipStationClient`: + +```ts title="src/modules/shipstation/client.ts" +// other imports... +import { + // ... + Label, + Shipment, +} from "./types" + +export class ShipStationClient { + // ... + + async getShipment(id: string): Promise { + return await this.sendRequest(`/shipments/${id}`) + } + + async purchaseLabelForShipment(id: string): Promise
